What can't you forget in Princess Pearl?

Princess Huanzhu, which must be broadcast in summer vacation, accompanied me throughout my childhood. I haven't relived it for many years, but there is a plot that I will never forget. That's Princess Zhu Huan 2 episode 18. The swallow left the palace in a rage because people around her always said that she was illiterate, with low academic qualifications and slow learning, and Mei and others could not find her anywhere. Yongqi regrets it very much. When the swallow left the palace, she made up her mind never to go back to the palace, so she also stayed away from the guest house of Liu Qing's brother and sister. Swallow was curious, entered a chess club, then gambled with the boss in the chess club, and finally ended up in the chess club. I was really afraid of these episodes when I was a child. I feel sorry for the swallow. She lost her freedom and had to eat leftovers. She was forced to work as a coolie every day. What I remember most clearly is that the swallow gnawed a corn-and-corn head piteously.
