Porcelain teeth are popular in entertainment circles. Both actors and actresses have bright and shiny big white teeth, which seem to have been poured out of a standard mold. They are the two front teeth in the middle, and the remaining teeth contract to both sides one by one, which conforms to the ancient tooth aesthetics and is also called "Hollywood White".

The Awakening Age is a hit on CCTV. This TV series tries to restore the real Chen Duxiu for us. As an actor, Yu Hewei naturally made great efforts, but after all, his temperament and skill are different. We only saw a Yu Hewei in a robe, especially "big white teeth", which made us very dramatic.

Chen Duxiu is a chain smoker. It is said that he loves to smoke cigars, and he is full of smoke all day long. At that time, he didn't have the ability to wash his teeth. He must not be full of big white teeth. Why can't Yu Hewei sacrifice his oral value, "age his teeth" and make his role closer to Chen Duxiu?
