重慶銅梁龍

Chongqing Tonglianglong was founded on 23 December 2021 by a group of investors led by the Chongqing Football Association, and the squad comprised mainly youth players from Chongqing Furen High School. Upon the club's formation, they bore a variant of a Beijing Renhe badge due to a former connection between the two clubs, and entered the 2021 Chongqing Amateur Super League as Chongqing Youth (Chinese: 重庆青年), a fifth tier of Chinese football. The club then won the Chongqing Amateur Super League after beating Chongqing Linxuan on penalties, and were promoted to CMCL, the Chinese fourth division.

Chongqing Tonglianglong were drawn into group D of the 2022 CMCL. After three games, Chongqing topped their group, with both them and Guangxi Lanhang advancing to the next stage. After a score of 13–0 on aggregate in the elimination round against Chongqing Benbiao, Tonglianglong were drawn into group B of the CMCL finals. After all seven games in the finals, Chongqing Tonglianglong secured promotion to China League Two after a 5–1 win against Jingchuan Wenhui on 14 November 2022, and qualified for a two-legged play-off tie to decide the outright winner of the season. After two 1–1 draws against group A winners Yuxi Yukun Steel, Chongqing lost 4–2 on penalties to settle for second place.

In the 2023 China League Two season, Chongqing Tonglianglong finished top of the South Group claiming 11 wins out of 14, and were qualified for the promotion stage. With three gameweeks to spare in the promotion stage, on 17 September 2023, Chongqing Tonglianglong secured promotion to China League One with a 3–0 win over Hubei Istar. One gameweek later on 10 October 2023, Chongqing Tonglianglong were crowned champions of the 2023 China League Two, after second-placed Dalian Zhixing lost their match against Yunnan Yukun.

While in the 2023 Chinese FA Cup, Chongqing beat CMCL outfit Rizhao Yuqi 6–1 away from home in the first round, and knocked out China League One side Shijiazhuang Gongfu 3–0 in the second round, meaning they would host Chinese Super League club and neighbours Chengdu Rongcheng in the third round. On 23 June 2023, with a 0–0 draw inside 90 minutes, the tie had to be decided by penalties, in which Chongqing prevailed 4–2. After beating fellow China League Two side Nantong Haimen Codion 3–0, they faced Chinese Super League side Shanghai Shenhua in the quarter-finals on 30 August 2023, in which Chongqing lost 2–0, ending their CFA Cup run.

On 9 March 2024, Chongqing Tonglianglong hosted Liaoning Tieren in their season opener. A Yaki Yen goal secured a 1–0 win for Chongqing Tonglianglong, claiming the club's first ever win in the division.
