He Xiaoqiang was promoted to the senior team of Beijing Guoan and made his debut in a 2020 Chinese FA Cup on 28 November 2020 against Chengdu Better City in a 1-0 victory.[1] The following season in June 2021, despite not having registered a single league appearance with the club's first-team, he was given an opportunity to play at a continental level, as Beijing and the other Chinese teams involved in the AFC Champions League group stage sent a mix of reserves and youth players to the centralized venues: in fact, most of the senior players were still dealing with self-isolating measures to contrast COVID-19 following international matches, so the clubs involved chose to keep them in China, valuing performances in the national top-tier league over ACL fixtures.[2][3] He made his continental debut in an AFC Champions League game on 29 June 2021 against Kawasaki Frontale in a 7-0 defeat.[4] On 23 December 2022, He made his league debut against Guangzhou F.C. in a 3-1 victory.[5]
