In A Dream of Red Mansions, at which festival did Xifeng tell the joke of "The deaf set off firecrackers"?

The fifteenth day of the first month is the Lantern Festival.

Background: In the second round of parcel delivery game, it was Xifeng's turn to tell jokes.

The original text is like this:

Feng thought for a moment and said with a smile, "The first half of the first month is also spent by the whole family. It's really lively. Grandma, grandma, granddaughter, grandson, grandson, grandson, grandson, grandson, grandson, grandson, grandson, granddaughter, grandson-everyone laughed at his words and said, "I don't know which one is the editor-in-chief?" You Shi smiled and said, "If you want to recruit me, I can tear your mouth off. ""Xi Feng "stood up, clapped his hands and laughed." I won't say anything when people say you are fooling around. Grandmother Jia smiled and said, "What do you think?" ? Hearing this, Xi-feng thought for a moment and said with a smile, "There's a room under this floor. After drinking all night, it's all gone. "。" ?

When they saw what he said in awe, the others had nothing to say, but they were all waiting dumbfounded, only feeling cold and tasteless.

A Dream of Red Mansions is the first of China's four classical novels, and it is a novel written by Cao Xueqin in Qing Dynasty. It is also called The Story of the Stone and Jinyuyuan. This book is divided into two editions: 120 Cheng Ben and 80 Fat Ben.
