The TV series "Do you know it should be green, fat, red and thin?" The confrontation between Cuba and China is in episode 57.

In this episode, Gu was very angry because he had an appointment with Qi Heng, but they didn't do anything out of line, so they couldn't vent. So when eating, Gu buried himself in bitter water and didn't say a word. Sister Rong was not happy to see her father, so she quickly spoiled. After dinner, Gu couldn't get angry, so he kept picking on him.

When Saint wanted Gu to rest, Gu ignored him and went to bed alone. The next day, after breakfast, Gu went to court, and then Sheng couldn't help it. Gu should have seen his relationship with Qi Heng, so he put his cards on the table.
