What episode is the doggerel read by Gege Wei Zi in New Zhu Huan?

Swallow finally came to Dali and met Xiao's aunt and uncle. The local people are singing and dancing, but the swallows always hold the letter basket left by Yongqi. Er Kang and Yong Qi suddenly met the eunuch who killed himself and took him down at once. The man confessed that the pursuit was ordered by the queen, and the emperor was furious and wanted to behead the queen and Sister Rong. Wei Zi took out the gold medal at the critical moment, escaped the death penalty of the two men, and stopped Sister Rong's flogging with a song "Don't hit poetry". The emperor ordered the queen not to leave Ren Jing Palace. The swallow decided to read all the letters, and he was so happy that he kept his mouth shut.
