This problem is actually related to heredity and acquired human habits. Some people are born with Chinese characters. Some people are acquired, such as athletes who have been practicing weightlifting since childhood, and they are not particularly tall. If you often knock your chin on the table to sleep, even a sharp chin will be flat. There is also a narrow face that looks sharp, but people will chew with their teeth on both sides after eating the day after tomorrow, and naturally their faces will gradually widen. Maggie Cheung's pointed face is the result of people insisting on eating with front teeth for decades! To sum up, there is a natural pointed chin, but it is possible that the pointed chin will also flatten the chin because of the acquired reasons!

Pure hand tour, hope to adopt.
