Zhou Yang Haiyan is an inactive professional Chinese player. He has played for different Vici Gaming squads for almost his entire career.

His career started in 2015 with Vici Gaming. 5 days after joining, the team rebranded to Vici Gaming Reborn. The team placed 1st at StarLadder i-League Invitational Season, 2nd at WCA2016 CN Qualifiers S1. Also after The International 2016: China Qualifier, where the team also won 2nd place, the team is only ranked 13th-16th at The International 2016 itself. Since the results of the reborn turn out to be clearly better Zhou gets to Vici Gaming. In this team Yang earns his most significant achievements in his career. Second place at World Cyber Arena 2016, first place at StarLadder ImbaTV Dota 2 Minor Season 1. Also, the not insignificant tournaments DreamLeague Season 11 and EPICENTER Major 2019 brought in a total prize money of $1,000,000. At The International 2019, Zhou stood out with his decent performance and took 5th-6th place.

While taking breaks from playing for Vici Gaming, Yang played for VGJ.Thunder. Zhou also achieved good results in this team, where he beat Evil Geniuses in the final of Galaxy Battles II: Emerging Worlds final. However, in 2018, the team failed to even reach the top ten at TI 2018. Immediately after the global Dota 2 tournament, VGJ.Thunder disbanded the team. Yang returns to Vici Gaming.

After a similarly successful period of his career at Vici Gaming, Zhou moved to Elephant 4AM and then returned to Vici Gaming. In June 2024, Yang attempted to qualify for The International 2024 as part of Team Turtle, but was unsuccessful. In the spring of 2025, Zhou returned to VG.

In January 2026, Yang joined the Yakult Brothers, but left the team in March. In April, he became part of the Chinese team Team Refuser, which also included Zhang Paparazi Chengjun.
