"In order to bring back these three children, I built ten official seals alone. I can hardly remember how many people I dealt with back and forth." Liu Eryong recalled that the three children were practicing weightlifting in a sports school in Guangxi at that time, but they were slow to achieve results. It is time to leave school when they are old. For those who have not achieved results, the greatest possibility is to go directly to the society to work to earn money and bid farewell to weightlifting completely. Seeing that the three children actually have potential and meet the requirements of small levels, he proposed to introduce the three children back to Qingdao. "The introduction of children is not a trivial matter. In case they come to become champions, Guangxi Sports Bureau will hold the local coaches accountable. Therefore, the leaders of the Sports Bureau found the five coaches of the three children to sign and stamp their respective signatures to express their willingness to give up the children. The Municipal Sports Bureau and the Provincial Sports Bureau instructed them to sign and enter Shandong after the release. If the three children cannot practice, we will also bear certain responsibilities. Finally, we will cover ten chapters and have been busy for more than a month. The three children will be brought back. " Today, Liu Eryong also thinks that it was a very successful aid for them. Three Guangxi children came to Qingdao to study hard.
