On November 2, Beijing time, the Volleyball Sports Management Center released the 2021 National Boys' Volleyball Training Notice, and Shandong Team An Zhiming was selected, and he is the son of An Jiajie, a popular candidate for the new manager of the Chinese women's volleyball team.

According to the announcement of the Volleyball Sports Management Center, the national boys' volleyball team, which is coached by Gong Zaifeng, will conduct closed training in Weifang, Shandong, from November 8 to December 28. A total of 16 team members were selected for the national junior boys' ranking list, two of whom temporarily did not participate in the training, and Shandong and Jiangsu became the two teams that transported the most talents. Especially in the shandong men's volleyball echelon with outstanding achievements in the past two cycles of the youth army, a total of 5 people were selected for this training, including An Jiajie's son An Zhiming, who was praised by netizens as "tiger father without dog". According to Shandong media reports, during the period when An Jiajie was closed with the Chinese women's volleyball team to prepare for the 2019 Women's Volleyball World Cup, he did not go home to meet his wife and children for up to 8 months, but he was quite satisfied that his son could inherit the mantle and gradually emerge.
The 49-year-old An Jiajie, with a height of 2 meters 02, was the main receiver of the Chinese men's volleyball team and had outstanding offensive strength. After retiring from the army, An Jiajie transformed into a coach and successively served as the head coach of the Shandong men's volleyball team and the Shandong women's volleyball team. In 2013, Lang Ping went out of the mountains for the second time to take charge of the Chinese women's volleyball team, and An Jiajie was selected as an assistant. After winning the gold medal with the Chinese women's volleyball team at the Rio Olympic Games, An Jiajie was promoted to executive coach of the Chinese women's volleyball team, and was entrusted by Lang Ping with a heavy responsibility, independently leading the team to participate in competitions including the Swiss Women's Volleyball Elite Tournament and the World Women's Volleyball National League. Although there are still many voices questioning An Jiajie's independent leadership results, he is still the hottest candidate to succeed Lang Ping as the head coach of the Chinese women's volleyball team.
