Happy birthday to you

The expression “Happy Birthday” appears in the birthday gathering as a simple song whose social meaning exceeds its musical content. Song Yun'er offers it to celebrate the birthday of Lu Cheng's mother, and her performance briefly establishes her as the evening's publicly recognized favorite. Yet the song's very familiarity also makes it vulnerable to criticism: it wins praise for Song Yun'er's sweet voice but is dismissed by others as conventional and lacking novelty. Its recurrence later becomes a subtle challenge when Song Yun'er asks Su Xiangcheng to perform another instrument and Su Qingrou pointedly questions whether she can play even the same birthday song on the violin.

A Public Offering at the Birthday Gathering

Song Yun'er introduces the song by volunteering to perform for the birthday celebration before Su Xiangcheng can finish speaking. Her intervention quiets the room immediately. The action is presented not merely as a musical contribution but as a calculated entrance into the gathering's hierarchy: Song Yun'er is widely known in that social circle as Lu Xun's idealized woman and Lin Yancheng's girlfriend, so her choice to sing carries the prestige of her public identity.

The song's brevity reinforces its function as a ceremonial gesture. The familiar birthday refrain is completed quickly, satisfying the basic requirements of the occasion without creating a demanding artistic encounter. Song Yun'er's voice is nevertheless described as sweet and captivating, allowing the performance to succeed at the level of charm even as it remains limited at the level of originality. Some guests praise her; others disdain the simplicity of the number. The divided response shows how the same song can operate simultaneously as sincere celebration, social display, and evidence of the performer's limitations.

Familiarity, Favor, and Social Competition

After Song Yun'er begins, Lu Xun's so-called sisters and older sisters start competing to perform. Their performances follow the birthday blessing while invoking the name and influence of Lu Xun, making the gathering resemble a contest for favor rather than a purely familial celebration. In that setting, “Happy Birthday” becomes the opening move in a chain of carefully staged compliments. Its plainness is useful because everyone recognizes its purpose at once: it marks loyalty to the birthday recipient while allowing the singer to occupy the center of attention.

The song also clarifies Song Yun'er's position among the guests. She does not need an elaborate composition to be noticed; her reputation makes a routine number socially effective. At the same time, the simplicity that helps the song communicate instantly prevents it from establishing unquestionable artistic superiority. The performance can be celebrated as graceful and criticized as unimaginative without contradiction, because its main power lies in public recognition rather than technical complexity.

The Song as a Test and a Provocation

Later, Song Yun'er approaches Su Xiangcheng and remarks that she has heard Su Xiangcheng is proficient in instruments beyond the piano. She proposes that Su Xiangcheng perform something more for the happy gathering, naming the violin, zither, and accordion as possibilities. The request appears generous, but its timing and direction turn the earlier birthday song into an implicit standard: Song Yun'er has already performed, and now she pressures Su Xiangcheng to demonstrate whether she deserves comparable attention.

Su Xiangcheng answers by closing the piano and inviting Song Yun'er to choose the instrument, suggesting that they play whichever one Song Yun'er selects. Song Yun'er picks up the violin but sets it down almost immediately, becoming visibly awkward. Su Qingrou then intervenes with a mocking comparison, pointing out that Song Yun'er's performance was essentially the birthday song and asking whether she would be unable to play that song on the violin. Song Yun'er responds angrily, breaks free from Su Qingrou's grasp, and leaves arrogantly.

Contrast with Su Xiangcheng's Performance

Song Xiangcheng's response to the challenge shifts the gathering from easy ceremonial praise toward a more exacting musical comparison. After Song Yun'er departs and the room reacts with sighs, Su Xiangcheng walks to the zither and announces that Lu Cheng's mother loves “High Mountains and Running Water.” Unlike the familiar birthday song, the selected piece is presented as a deliberate attempt to honor the recipient's particular taste rather than merely fulfill a public ritual.

The contrast gives the expression its clearest narrative significance. Song Yun'er's song is short, recognizable, and socially efficient; Su Xiangcheng's chosen performance promises greater effort, specificity, and artistic risk. The first number helps establish the atmosphere of favor-seeking competition, while the second exposes the difference between being applauded for one's position and earning attention through ability. The expression therefore marks the threshold between ceremony and contest: what begins as a routine birthday blessing becomes a means of measuring status, confidence, and authenticity.
