Which episode is Princess Gertai becoming Xu?

When Qianlong learned that Yongqi was taking people to rob Zongren House, he flew into a rage and immediately ordered Foran to lead troops to find everyone. I didn't expect Fallon to see a group of people driving a carriage ready to return to the palace before he left the city. Fallon had a premonition that something was hidden, so he immediately took everyone to see Gan Long.

After seeing Ganlong, everyone begged. Ganlong thinks that the starting point of all this is out of his own compulsion on Xia, and finally his attitude softened, he forgave everyone and accepted it. However, when Qianlong decided to imprison the queen who abused lynching in Zongrenfu, Yong Qi, Wei Zi and others actually interceded for the queen, which surprised Qianlong and forced him to give up.

Although Qianlong recognized Wei Zi and saved the swallow from the death penalty, the marriage between Erkang and Saiya Skirt could not be cancelled.

In order to help Erkang, Ertai deliberately accompanied Saiya Skirt to travel and play games, which eventually made Saiya Skirt change her mind and insisted on not marrying Ertai.

Under the expectation of everyone, Qianlong made a decree to seal Wei Zi as a "pearl princess" and betrothed it to Er Kang; Swallow changed her name to "Princess Zhu Huan" and married Yongqi, while Princess Saiya of Tibet married Ertai. The case of Princess Gege in Zhu Huan ended successfully, but the stories of these young people will never end easily.
