Douluo Continent

I have explained this question before. I saw some book friends asking it, so I will say it again.

Girls develop earlier. If you are familiar with the current height trends of children, you will understand. For example, my wife was 1.7 meters tall when she was 11 years old, and she is only 172 meters now. Girls mainly develop in the last few years of elementary school, unlike boys.

Children's development mainly occurs in junior high school. Among the people I know, there are many girls who are 12 years old and 1.7 meters tall. There is a relatively strong girl who was 181 when she graduated from elementary school at the age of 12. Now she is only 183 in her 20s.

When I was 12 years old, I was 158, when I was 15, I was 181, when I was 18, I was 190, and then it stopped growing.
