Xu is a typical left-behind student in mountainous areas. His mother, Cao, went to work in An a few years ago, and his father, Xu Heping, went down the well all the year round to work hard for this family and provide schooling for his younger siblings. In 2006, Xu took part in the senior high school entrance examination. The family refused to give up and paid 5,000 yuan to the school to let him enter.

After entering high school, Xu Rong Geng decided to take the road of sports. He is 1.7 meters tall. He won the champion of 5000-meter race walking and 3000-meter race walking in the first middle school sports meeting in Shangluo City, and was awarded the "Sports Morality and Fashion Award". He is going to take a major in April, and he is going to apply for the Provincial Institute of Physical Education.

Xu's friends think that Xu is cheerful, lively, good-natured and "very sunny". There is a photo in Lareina C's mobile phone. In the photo, Xu is wearing a sportswear with half a basketball on his head and a smile on his dark face.

Due to the limited school space, there is no male dormitory. After attending middle school, Xu rented a private house in the county town and rented 80 yuan every month, which gave him more freedom.

The landlord's evaluation of Xu is that the child is very polite and can still sit still before the second year of high school. From the third year of high school, he often went out to play and didn't study hard, sometimes he didn't come back for a few days. I often drink and play cards with my friends in the house. Sometimes I can play all night.

These friends include Wu Ming and Lareina C, as well as Peng Lina, a senior two female student in Shangzhen Middle School who died in February 10, 2009.

Although the family pays 100 yuan a week for living expenses, it is obviously not enough for Xu, a student who has extensive friends and likes parties, so he often borrows money from his neighbors. Although it can't be returned on time, it won't breach the contract.
