Tai Er Suan Cai Yu

Tai Er Suan Cai Yu (太二酸菜鱼), also presented in the group’s current brand materials as New TAIER · Fresh-ingredient Sichuan Cuisine, is a restaurant brand within Jiumaojiu Group. The group’s official history records that it launched Tai Er in July 2015 as part of its move toward a multi-brand restaurant business. The brand is associated with suan cai yu, a Chinese fish dish prepared with pickled vegetables, and the company describes its approach as focused on making fish and continuing to develop its offerings. The brand is evolving beyond a narrow single-dish description. Jiumaojiu’s official website says that from March 2025 Tai Er began rolling out a “5.0 fresh-live model” store format, with changes to products, environment and service and a focus on live fish, fresh beef and fresh chicken. The group says that in 2026 the brand continued this upgrade through “New TAIER · Fresh-ingredient Sichuan Cuisine” stores, broadening the menu concept around live fish, live shrimp, fresh beef, fresh chicken and fresh pork. These descriptions represent the group’s stated brand direction and do not establish that every location has adopted the newer format. Tai Er belongs to Jiumaojiu Group, a Chinese restaurant group that says it operates multiple restaurant concepts. The group reports that its brands together had about 600 stores as of October 2025 and that its overall business covers China and has expanded overseas into Southeast Asia, the United States and Canada. Those figures and markets are group-wide; the supplied material does not specify Tai Er’s own store count or country-by-country footprint. Jiumaojiu International Holdings Limited, the group’s core company, was listed on the Hong Kong Stock Exchange on 15 January 2020 under stock code 09922. The group office is in Guangzhou, Guangdong.

Tai Er is a restaurant brand developed by Jiumaojiu Group. The group’s published history dates its launch to July 2015, describing it as a new brand that marked the beginning of the group’s multi-brand development. The name and brand identity are closely associated with suan cai yu, and the group’s current brand introduction continues to describe Tai Er as a brand focused on making fish and innovating its products. Jiumaojiu Group’s broader development provides the corporate context for Tai Er. The group traces its origins to a Shanxi-noodle shop established in Haikou in 1995. It later expanded its noodle business to Guangzhou, opened a Guangzhou shop in 2003, and established a Guangzhou headquarters in 2005. The group says it began a nationwide expansion in 2011. Tai Er’s 2015 launch was followed by the group’s 2020 Hong Kong listing and continued additions to its multi-brand portfolio. The group’s official timeline records that it incubated the hotpot brand Song in 2020 and opened the Guizhou sour-soup hotpot brand Shan De Shan Wai Mian in 2024. These are developments in the parent group’s history, not acquisitions of Tai Er. In March 2025, Tai Er began introducing a 5.0 “fresh-live model” store format. According to the group, the store upgrade addresses products, dining environment and service, and highlights live fish, fresh beef and fresh chicken. In 2026, the group described a further evolution under the “New TAIER · Fresh-ingredient Sichuan Cuisine” identity, with fresh-ingredient stores and a Sichuan cuisine matrix built around live fish, live shrimp, fresh beef, fresh chicken and fresh pork. The official material presents this as an ongoing brand upgrade; it does not establish a full conversion of all Tai Er locations. The brand operates within Jiumaojiu Group, whose core company, Jiumaojiu International Holdings Limited, was listed on the Hong Kong Stock Exchange on 15 January 2020 as HK.09922. The group says its portfolio totals about 600 stores as of October 2025 and that it operates across China and has expanded into Southeast Asia, the United States and Canada. The source describes these as group-level figures and does not provide a separate Tai Er outlet count. The group office address listed on its website is in Guangzhou, Guangdong.

  Freshly Killed Fish Claim Questioned as Stores' Actual Supply Practices Draw Scrutiny

  In September 2025, questions arose over whether some Tai Er outlets were actually killing fish fresh on site. Parent company Jiumaojiu responded that the upgrade of outlets to the fresh-kill model was being rolled out gradually, with 68 such stores at the time, and that it planned to complete the conversion of all stores. This entry distinguishes upgraded outlets from existing ones and documents the dispute over how the claim was communicated to customers.
