Punishing Wei Zi is that episode.

Swallows and others were sent to the ancestral temple of Lengruhan Palace for the crime of deceiving the monarch. Not only is it dark, but I have to associate with cockroaches and mice every day, and my life is miserable. Unexpectedly, before Zongrenfu received the order of Qianlong, the queen tried Xiaoyan and others by private rights, and even abused lynching, hoping to get three people to confess. Wei Zi didn't know the reason, thinking that Lord Liang was sent by Qianlong, so he was extremely disappointed with Qianlong. Therefore, they had a tough attitude towards Liang Zhu's confession and refused to plead guilty, so the three were tortured and scarred by Liang Zhu. Adult Liang saw that the confession could not be made, so he had to put the three people in jail again.
