The tradition is that the "birthdayboy" or "birthday girl" should fill their mouth with as many long noodles as they can and then eat them.
传统是“男寿星”或“女寿星”应尽可能往嘴里塞满面条，然后吃掉它们。

The birthdayboy has been dead since 479 B.C., but one wouldn’t necessarily know that from the sign outside: this was the “second annual” birthday party at the Confucius Temple.
孔子于公元479年逝世，但人们不一定会通过外面的标语“孔庙第二届祭孔大典”得知这些。
