Chen "M1ssion" Hsiao-Hsien (Hanzi: 陳孝銜) is a League of Legends esports player, currently mid laner for Machi Esports. He was previously known as DonSan.


DonSan joined the Taipei Assassins as a substitute Jungler and Mid Laner in late 2014. But since the team's Junglers Winds, Sarsky, DinTer and Mid Laners Chawy, Achie were performing well during that time, DonSan never played a single game on stage.

2015-2016 Season[edit]

In mid 2015, Midnight Sun Esports' coach Lilballz invited DonSan to join his team as their starting Mid Laner as the team's previous Mid Laner Wish has just left the team. DonSan accepted his offer and renamed to M1ssion. After joining the team, they participated in the LMS 2015 Summer Promotion and won the relegation match against armature team Donate Me Please to secure themselves a spot in the LMS 2015 Summer Split.

During the Summer split, M1ssion shared the starting Mid Laner role with Korean import CaNdy before CaNdy was banned from competitive play for six months for accepting offers from the other teams without notifying MSE's management.

In the 2016 Season, M1ssion played for all of MSE's games but the team failed to make playoffs in both splits, placing 6th in the 2016 Spring Split and 5th in the 2016 Summer Split. After the summer split, Midnight Sun Esports' LMS spot was acquired by Fireball and M1ssion joined Fireball.

2017 Season[edit]

M1ssion played both Top Lane and Mid Lane during his time in Fireball. However the team did not perform well and was placed 6th in the 2017 Spring Split, once again unable to make it to playoffs. During the break between the spring and summer split, M1ssion left the team to join the newly rebuilt Hong Kong Attitude and replace their previous Mid Laner Gear due to management conflicts.

Hong Kong Attitude had a mediocre performance in the 2017 Summer Split and ended in 6th with a 7-7 score, meaning that the team was out of playoffs. However since Flash Wolves and ahq e-Sports Club qualified for Worlds, HKA was allowed to participate in the Taiwan Regional for the 3rd seed at Worlds. HKA proceeded to win both games against J Team and Raise Gaming and qualified for Worlds as LMS' 3rd seed.

At Worlds, HKA was placed in Group D with Turkish team 1907 Fenerbahçe Esports and Japanese team Rampage. HKA placed 2nd in the fist round and faced Fnatic in the second round, losing a quick 0-3 and knocked out of Worlds.

During the pre-season, Hong Kong Attitude and ahq e-Sports Club agreed to swap players and swapped M1ssion for Chawy.


  • Was known as 東山街惡少 or 東山 before joining the competitive scene.
  • Nicknamed 電競佣兵 (the esports mercenary) in Taiwan for frequently changing teams.
