Hi my friends. How old is mature? No definition. Some people are 60 or 70, but they still look like a kid.大家好，多少岁才算成熟？这个没有定义！有些人60多，70岁了还跟小孩子一样！
Some people are just 20, but they look very mature. It’s all based on how much painful things and experience you have. 有些人才20多岁，看起来就已经很成熟了！这取决于你经历了多少痛苦和人生经历！Happy people are not that mature, mature people are not that happy. 快乐的人，往往没那么成熟！而成熟的人，又往往没那么快乐！
