Which episode is the swallow wiping tears with a dragon robe?

Gan Long finally listened to the queen and asked Mammy Rong to teach the rules of swallows. The swallow saw that he couldn't push it off this time, so he had to learn the rules willingly. But I don't know if the swallow really doesn't have the talent to learn the rules, or if Sister Rong deliberately makes things difficult, but the swallow just can't meet the standards required by Sister Rong. In a rage, the swallow tried to escape in disgust. At this time, Gan Long came to visit. He was furious when he saw the swallow, but the swallow didn't know how to look at his face. He even added fuel to the fire and refuted Gan Long. In a rage, Gan Long decided to hit the swallow's twenty boards again. Fortunately, Yong Qi, the imperial concubine and others pleaded with him, and Gan Long ordered it to stop. But at this time, the swallow was badly hurt, but he still felt sorry for Wei Zi.
