Zhu Huan Gege lost the show, which episode did Yongqi receive?

The first episode, 16, tells that a group of people arrive in a town, and a large family in the town is holding a hydrangea throwing ceremony to get married. It's very lively, and everyone is curious to see it. Naughty little swallow, seeing the beautiful married girl and the hydrangea that so many people are grabbing, jumped up, caught the hydrangea and threw it at Yongqi. Yongqi was surprised and returned the hydrangea to the swallow.
