西安龍海FC

Xi'an Ronghai Football Club was founded in January 2021 by Yang Xiaolong, the owner of the now-defunct Xi'an Wolves, registering as a member of the Xi'an Football Association. In May 2021, they participated in the Xi'an FA Cup, and after winning five matches out of a possible five, they were crowned winners, becoming eligible to compete in the 2021 Chinese Champions League (CMCL). In the regional competition, Xi'an Ronghai topped their respective group, grabbing two wins and a draw, which set up a place in a play-off to progress into the final round. After beating local opponent Xi'an Hi-Tech Yilian on penalties, the club advanced into the final sixteen. They were drawn into Group C which consisted of Jinan Xingzhou, Jiangsu Zhongnan Codion, and Yuxi Yukun Steel, Xi'an Ronghai finished bottom, putting an end to the season, ranked 16th. In the 2022 CMCL season, Xi'an Ronghai finished second in their respective group, but were knocked out by Tianjin Fusheng in the elimination play-off round.

By April 2023, the club rebranded its name to Xi'an Chongde Ronghai Football Club. They were slotted into the Changzhi region, where, after picking up three wins, one draw, and a loss to Langfang Glory City, they progressed into the final round. After the seventh match against Shenzhen Juniors that could have seen Ronghai jump to first place and subsequently win promotion, Xi'an Chongde Ronghai finished in second place, entering the promotion play-offs. On 21 October 2023, Ronghai hosted Guangxi Hengchen in the first round, which ended in a loss for Ronghai through a penalty shoot-out, missing out on promotion. By 6 February 2024, Xi'an Chongde Ronghai were not included in the initial list of teams in the 2024 China League Two. However, Xi'an Chongde Ronghai were confirmed a spot on 22 February, a few days after Jinan Xingzhou announced its dissolution. During this period on 20 February, the club appointed Wu Yan as their new head coach.

On 15 March 2024, a week before the upcoming China League Two season, Xi'an Chongde Ronghai announced that they would use Shaanxi Province Stadium as their home ground, groundsharing with fellow China League Two club Shaanxi Union, who they form a Shaanxi derby in the professional leagues with, for the first time in twenty years in Shaanxi football history. On 5 April 2024, in a 2–2 league draw with Dalian K'un City, Gong Zheng scored the club's first professional goal. On 11 April 2024, after a single home league game, Xi'an Chongde Ronghai reached out to the public to resolve issues with their home ground, as they could not remain financially stable if they kept using Shaanxi Province Stadium. By 15 April, the club started using Xi'an Olympic Sports Center as their home ground. Shortly after a home league match against Langfang Glory City on 11 May which took place at Fengdong Football Park, on 14 May, the league announced that home matches for the rest of the season will take place at the Yan'an National Fitness Center, in Yan'an, Shaanxi, which was previously not an option, as Xi'an Chongde Ronghai were registered in the Xi'an Football Association, a city-based regional football association, and a move outside of city limits was not permitted. On 22 May, the club announced a change to its name, Yan'an Ronghai Football Club, and unveiled its new club badge, in anticipation of finalising a permanent move to Yan'an after the end of the 2024 season.
