The word "flashy" comes from something related to Chu Yang's father.
During the Spring and Autumn Period, Chu Yang, a doctor from the State of Jin, went to the State of Wei and came back to pass by Yining to stay in an inn. The owner, surnamed Wen, admired Chu Yang's father's handsome appearance and extraordinary behavior, and quietly said to his wife, "I have long wanted to find a person with noble character, but I have been paying attention to it for many years, but I have not found a satisfactory one." Today, I think Father Yang is a good man, and I am determined to go with him. "With the consent of Chu Yang's father, the shopkeeper left his wife and followed him. Along the way, Chu Yang's father and the shopkeeper rambled and didn't know what to talk about. The shopkeeper walked and listened. Just out of Yining County, the shopkeeper changed his mind and broke up with Chu Yang's father. The manned wife saw that her husband suddenly turned back, and her heart was unknown, so she asked. "How do you meet such a person, how to refuse to accept him? Aren't you determined? You can rest assured of things at home. ""I think he is good-looking and I can trust him, but after listening to his remarks, I feel disgusted. I am afraid that if I go with him, I will not get an education, but I will suffer and give up my original idea. " The owner said. In the eyes of the shopkeeper, this father is a "flashy" person. So the shopkeeper resolutely left him. Source "Zuo Gong Five Years"
