What shortcomings do you think Yu Zaixi has?

He is very low-key and modest. He doesn't drive a luxury car, show off his wealth and waste it. His performance in the program is very natural, and he knows how to set off and guide the guests, instead of taking himself as the center and relying on exaggerated expressions, lines and gestures. The most classic expression is a stunned face. But he also has many shortcomings, that is, he loves to nag and always nags about one thing.
