1. Gu Qianfan drank tea at Zhao's Tea House. The passage about the needle on the wasp's tail comes from "The Lion's Roar" in the Ming Dynasty. It tells the story of Su Shi's friend Chen Jichang who was afraid of guilt. Therefore, this sentence seems to call Zhao Pan'er a poisonous woman. In fact, the screenwriter has given Gu Qianfan a plan to dote on his wife. It’s a drowning persona.

2. Gu Qianfan went to Yang Yunpan’s house to pick up the painting. The lady came out and scolded Gu Qianfan for being a bastard like his father even though he came from a Shili family. This would be mentioned in more than thirty episodes later when Zhao Pan'er asked Chi Pan about Gu Qianfan's life experience and knew that Gu Qianfan's father was Xiao Qinyan. There are only one family on the left and right, one family is Chipan's family, and the other family's daughter married to Qiantang and is Mrs. Yang.

Please pay attention, until the thirteenth episode, Gu Qianfan didn't drink it. The last time Pan'er poured him a sip of tea was in the first episode, when Pan'er saw him showing the Huangcheng Division's sign and deliberately overturned the tea. The second time and the first episode, Gu Qianfan poured the tea because he said it was poisonous. The third time was when he asked for a drink in this inn, and Sun Sanniang knocked him unconscious. The fourth time was after Pan'er's tea house opened, Pan'er poured him tea, and the seal rushed out to tell Gu Qianfan not to blame Pan'er, and Gu Qianfan left. The fifth time was still at the tea house. Sun Sanniang rushed out and said that Gu Qianfan was responsible for the bad business, and Gu Qianfan left again.

4. At the end of the third episode and the beginning of the fourth episode, Pan'er borrowed money from Gu Qianfan. Gu Qianfan said that he had no money. Pan'er said that I have something to change careers with you? Later, Pan'er said that he would give him his father's jade. This jade was dug from his sword and was called the jade sword head. Later, when Pan'er wanted to pay him back the money, he said that it should be enough for him to redeem the jade sword head. I jumped off the carriage and looked at his sword. At that time, the sword was inlaid with a jade sword head. At this time, Gu Qianfan had no money. He dug gold from the token. After giving the gold to Zhao Pan'er, he probably took the head of the jade sword. Later, the jade was no longer on his sword.
