Which episode is Erkang, the third burial holiday of Huanzhugege?

In the 30th episode of the third part, in the 31st year of Qianlong's reign, outside Beijing, Qianlong rode a horse with swallows in front, followed by officials from civil and military departments to greet Yongqi, which made him sad. Yongqi carried Erkang's coffin and finally walked back to Beijing. Yongqi is afraid of being close to home. She doesn't know how to face Wei Zi. She has a sad face, and Fu Heng behind her also has a solemn face. When the army approached, the swallow couldn't help running towards Yongqi. She had prepared a big basket of words to tell Yongqi, but now she forgot all about it! Yongqi hugged the swallow tightly, and the joy of reunion after a long separation and the sadness of losing Erkang merged into a complex emotion. What about Wei Zi the Swallow? Swallow shook his head, and the news of Erkang's death came. Wei Zi lost his mind and didn't want Dong Er. Yongqi can't help feeling sad. Fallon ran to Erkang's coffin, caressing it and crying. The sadness that white-haired people send to black-haired people makes others cry. I asked the emperor to let him take Erkang back to the bachelor's office. Gan Long nodded silently with tears, and the bachelor's office held a funeral for the body of Fakerkang.
