This time travel setting is so creative! Hu Yanxin, cousin, brother Niu - from their names to their identities, they are all full of contrasting comedy. A 22-year-old boy became a foot-washing maid, a 30-year-old cousin became a noble, and a 28-year-old tough man became a eunuch. Just thinking about the scene where the three of them met in the deep palace compound made me laugh.
