Delehei, from the prairie, was born in a "semi-sports" family in Hohhot. He said "semi-sports" because his mother is an athlete and his father is an army cadre. 180cm's mother and 188cm's father made Dele Black 207cm when he was only 15 years old. Deleher was born a big boy-9 kilograms, 8 ounces and 67 centimeters.

According to Deleher, although he was born heavy, he was slim. Deleher is particularly active in the womb, and may have inherited his mother's athletic talent. He is famous for his love of sports. If he doesn't walk, he runs on the ground with his feet. At the age of 7, little Deleher bought a full ticket by car, and the height of 130cm was at least half that of children of the same age. Since the third grade, Deleher has enjoyed playing football, joined the school football team and loved sports. In primary school, he could wear out two pairs of sports shoes a month. However, because playing football always hurts, Deleher's mother decided to let him take up other sports.

In June, 2000, 1 1, Delehei, a freshman, was 188cm tall. Under the arrangement of his family, he went to the Beijing Military Region Sports Team and officially joined the Bayi Team. He started his sports career at the age of 13.

After more than half a year's training in the handball team, in June, 20001year, the youth team of Bayi Men's Basketball Team discovered Deleher when selecting new players. They asked Deleher to do a bone test, and the test result showed that Deleher's predicted height might reach 2 14cm. As soon as the results came out, the Bayi Men's Basketball Team immediately made a decision to recruit this "future little giant". Before he officially joined the Bayi Men's Basketball Youth Team, Deleher had no real basketball experience, so his hobbies were even more out of the question. Unfamiliar sports, unfamiliar environment and unfamiliar life are all a big test for Delehe.
