The press’ nickname for him
Chun-hsin Tseng, who’s also known as Jason Tseng, is often referred to as the “Night Market Champion” by the Taiwanese media. The moniker came about as his parents used to run a store in Taipei that sold tanghulu, a popular traditional Chinese candied snack, in order to support his tennis career.
Tseng began playing the sport at five years old with his father, before enrolling in the famed Mouratoglou Tennis Academy in France when he turned 13. The Academy was founded by Patrick Mouratoglou, who was Serena Williams’ coach from 2012 to 2022.
He won his first singles title at 14
In 2015, Tseng won his very first singles title at Les Petits As, a junior tennis tournament for players between the ages of 12 and 14. He was also the first Asian to win the boys’ singles title.
The tournament has seen several of its champions, such as Rafael Nadal and Martina Hingis, go on to win Grand Slam titles over the years. And Tseng is on his way to following in their footsteps.
In 2018, he scored two Junior Grand Slam titles at the Roland-Garros (the French Open) and Wimbledon. That year, he also won his first ITF (International Tennis Federation) Futures event in Vietnam. During this time, he was ranked 444th in the world.
