We know that Qian is a good person. Qian is different from her sister Tang, and Qian uses magic to protect people. Although money thought Bailong was a bad guy at first because he hurt him, it was because Bailong was ordered by Tang to get his seal, and then money hurt him. But in fact, when taking us to see Qian, we all knew Qian was knitting a sweater in the room. He has superb magic, but his magic is not used to hurt people at all.
We know that Don is a bad guy. He once signed an agreement and detained many people here. Sign an agreement with them and take their names away so that they can never leave this place. Just like when I first came here 1 and needed to find a job, then Tang asked him to sign an agreement with him, so I signed this agreement with him. Don took his name and told him that now he started screaming. When Bailong told Chihiro, we knew that if we forgot our original names, we would stay here forever and never return to where we belong. You can see how bad their mother-in-law is from here. His worse place is reflected in other places, just as he trapped the white dragon here forever.
Comparing Tang with money, we can easily feel that Tang is a bad person.
