The old version of Huanzhuyan is an episode in which Gegehou and the emperor went to the folk.

The jealous queen has long been dissatisfied with Qianlong's long-term affair. This time, Qianlong actually got a daughter from the people for no reason, and was taken care of by the imperial concubine, which made her feel distressed and strongly rejected the swallow. However, Qianlong's whole heart has long lost its vows of eternal love with summer. So even though there are many unclear places in the process of confrontation, Gan Long still believes Xiaoyan is his long-lost daughter. In addition, the news of Xia Congyan's death made him want to take this opportunity to compensate Yanzi for his lack of love for his father for many years.

At the suggestion of Ji Xiaolan, the minister, Yanzi was named "Princess Zhu Huan" by Qianlong in the name of his adopted daughter, and was ready to announce it to the world at the ceremony of offering sacrifices to heaven. Wei Zi was surprised to find that the swallow turned into a princess at the ceremony. She intuitively decided that the swallow had betrayed herself, so she roared out of control in the street, only to be beaten by officers and men.

Erkang found something fishy and took Wei Zi home to recuperate. In addition, the detailed description of Xia events makes people begin to doubt the identity of the swallow.
