The Aesthetic Experience of the Blank Space in Dragon Restaurant

Okay, based on what you said about the detail of the "figure with an eyepatch from behind" (corresponding to the character Saifu, who as an adult stands guard at the stove instead of on the battlefield, the blurry figure Xu Fu sees when he returns to the ruins in his old age), I think your intuition is correct, and we can dig even deeper.

First, clarify the nature of this treatment

This is not "not making it clear," but rather "making it 99% clear, deliberately leaving the last 1%." The audience can piece together all the information—the legacy of the Dragon Restaurant, the dish name "Xu Fu's Braised Rice," the foreshadowing of the potato sprouts—only missing the action of "turning around, the two looking at each other, confirming identities, and embracing." Some people think this step should be added because adding it would indeed be "satisfying": the emotions have a clear outlet for release, the causal chain is completely closed, and the audience can leave with a "confirmed sense of completeness." But this is precisely the problem—satisfaction and lingering aftertaste are two different aesthetic benefits, and the former consumes the latter.

Why blank-leaving is more sophisticated here, broken down specifically:

1. Preserving imaginative space = the audience's right to participate actively
   Once the turning and embracing are added, the director makes the final judgment for the audience: this is a real reunion, and the emotion is confirmed. Without it, the audience must make the choice themselves—"Is this a dream or reality?"—and this choice itself is an emotional investment. The answer you fill in yourself has a stronger hold than one fed to you, because you have expended mental effort for it. This is also why online discussions split into the "dream theory" and "reality theory" camps, both of which are self-consistent—blank-leaving transforms the audience from "receivers" into "co-creators."

2. The peak of the emotional curve: the moment before reunion is the peak of emotional intensity
   The point you raised is actually a key aesthetic principle: anticipation itself carries energy; once it is fulfilled, the energy is released and begins to decline. The war, twenty years of separation, the death of Ma Junsheng, Saifu's transformation from holding a gun to holding a ladle—all this tension ultimately converges on the moment of "about to recognize each other." If the camera pushes forward one more step to show the confirming embrace, the audience's emotions would peak at that second, then naturally begin to decline, and by the time the end credits roll, the emotions would have already cooled significantly. Stopping at the "figure from behind" means the audience leaves the theater with the emotional tension still unreleased—this unfulfilled peak will continue to resonate in their hearts, which is what is meant by "strong aftertaste."

3. The theme of "doing good without expecting reward" requires this sense of incompleteness to match
   The comment you found actually points out a logic: Xu Fu's character's action logic has always been "saving people without expecting anything in return." If the film arranged for him and Saifu to confirm their identities and have a grateful reunion, it would be using a narrative logic of "karmic reward" to pay off an originally "unconditional" act, which is slightly pretentious and redundant in terms of values. Leaving a figure from behind precisely preserves the more sophisticated idea that "kindness doesn't need to be confirmed to be valid"—the audience knows it's him, Xu Fu himself might also know, but the film doesn't need an embrace to "prove" that it happened, because it has already been fully proven through the dish "Xu Fu's Braised Rice" and the potato sprouts in the ruins.

4. Restraint actually strengthens the "universal sense," preventing the narrative from being hijacked by emotion
   The cooling issue you mentioned also has another layer: if the recognition were dramatized, that moment would become "the endpoint of Xu Fu and Saifu's private story"; but stopping at the figure from behind pushes it back to a more macro, more symbolic position—this is not just a reunion of two people, but a metaphorical presentation of the idea that "kindness leaves a spark." Once private emotions are concretely realized (expressions, dialogue, embrace), they become concretized and narrowed; blank-leaving allows this moment to hover between an individual story and a universal allegory, allowing the audience to project their own emotions into it.

So your point that "even this treatment is a bit redundant" also has merit—the action of Xu Fu seeing the figure from behind, if handled even more lightly (e.g., a fleeting glimpse, or even not giving a clear reaction shot of him "seeing"), might be more thorough than the current intermediate state of "giving a hint but not revealing it." The "final step" your friend wants is essentially about wanting confirmation; while the film (and the direction you appreciate) wants to preserve suspension—letting the audience leave the theater with their own answer that hasn't been taken away, which is in itself a more enduring aesthetic experience than "satisfaction."

Bluntly put, the reason blank-leaving is "good" boils down to one sentence: It trades certainty for possibility, and possibility is more worth savoring than certainty.

Broken down into the most essential points:

1. Once information is fully given, the feeling reaches its end.
   You see the embrace, and the matter is "complete," the emotion is like a glass of water poured out, with no remainder. You don't see the embrace, only the figure from behind, and the matter is "incomplete" in your mind—and the brain involuntarily revisits and fills in incomplete things repeatedly. Blank-leaving isn't about making the audience "guess," but about making their emotions burn continuously rather than "extinguish." This is the most direct benefit: it prolongs the duration of the aesthetic experience.

2. The answer the audience fills in themselves is more convincing than the answer the director gives.
   Adding the embrace is the director's judgment; the audience can only accept it or not. With blank-leaving, the audience pieces together "this is Saifu" themselves, and this conclusion is drawn by you, so you believe it more and cherish it more. This is why blank-leaving is often more "moving" than direct presentation—not because the content itself is more moving, but because "figuring it out yourself" carries its own sense of satisfaction.

3. The peak cannot be crossed; crossing it means going downhill.
   Emotion is highest at the point of "about to reunite," because that moment contains both the tension of "past hardship" and "future completeness." Once the reunion is fulfilled, the hardship is repaid, the future is delivered, and the tension returns to zero. Blank-leaving is about stopping the film at that highest point, using the peak as the ending—you leave with peak emotions, not with emotions that have already begun to decline.

4. Simply put, "what is not said" occupies your time longer than "what is said."
   Clearly explained content, you finish watching and archive it. Unexplained content, you will mentally revisit it repeatedly—this is the physical mechanism of "aftertaste." Blank-leaving doesn't create "beauty," but lingering thoughts, and lingering thoughts are precisely what keep a film in your memory and in your life for a long time.

In one sentence: When it's fully given, the audience "knows"; when blank-leaving is used, the audience "thinks"—and the act of "thinking" itself is where the aesthetic experience truly takes place.

Yes, this formulation captures a more essential layer—the difference between showing vs. telling.

Stopping at the figure from behind, the camera is still "recording a scene that is happening right now," and the audience is in the same viewing position as Xu Fu: we see the same figure from behind as he does, we are equally guessing, equally holding our breath. At this point, the film is immersive—you are not being "told" something, you are "experiencing" something, on the same cognitive level as the character, and the emotions are synchronous.

Once you push forward, letting the camera turn around, showing the confirming face and embrace, the film's posture changes: it is no longer "watching with you," but stands above you and the character, using an omniscient tone to say "okay, this is how it is, they recognize each other." This step inherently carries a flavor of "the narrator stepping in to explain the ending"—even without a single line of dialogue or narration, the mere camera movement itself is a gesture of "telling," pulling the audience out of the character's perspective and turning them into a listener being informed of the outcome. This is the source of the "deliberate" feeling: not because it's sentimental, but because it exposes the hand of the narrative, making you aware that "someone is telling me a story," rather than "I am watching this happen."

So the distinction you made is particularly accurate: "showing" keeps the audience inside the situation, with emotions growing from within; "telling" places the audience outside the situation, feeding them a ready-made conclusion. The reason blank-leaving is not deliberate is precisely because it refuses to cross this line—it would rather let the audience leave with an unresolved image than use a "final step" to turn itself into a condescending narrator.

This is actually why many restrained endings choose to "freeze the action in mid-motion" (a hand reaching out but not yet touching, a door not yet fully closed, a head turning but not yet fully turned)—mid-motion images always belong to "happening now," while only completed images are read as "already happened and been explained." The former keeps the audience present; the latter escorts the audience out, adding a final "the story is over."
