Even having made some small mistakes at the National Games, the experience in Tokyo has helped Luo maintain a peaceful state of mind to calm down.
"I didn't do well in Tokyo and it damaged my confidence," Luo said. "But as I prepare for the National Games, I adapted myself and improved the equestrian skills, the victory in this campaign is a boost for me."
Coach Cao Zhirong, who took the silver in London Olympics, didn't attribute Luo's failure in Tokyo to his skills but mentality.
"He paid too much attention to the result and can't go back, so we sought to revive him by making him believe his skills," Cao said.
To the 24-year-old, the hard-won gold medal is an affirmation and encouragement for the efforts he has paid in the past years.
Actually, Luo started his sporting career in rowing in 2006. Accidentally, the young boy was charmed by the "cool" sport, which includes fencing and equestrian, when his first coach Qian Yinghao took him to visit the Shanghai modern pentathlon team.
During the Rio Olympic cycle, Luo made it to the national team as a ladder player for Cao.
In Cao's opinion, the experience of a ladder player has laid solid foundation for Luo's future.
"Preparing for the elite events such as Olympic Games as a ladder player, the experience let him know how the national team prepares and grow up," Cao said.
After being called up to the national team as a player in 2017, Luo proved himself by taking a bronze medal in the 2018 Jakarta Asian Games.
