Several sources say Jian Xin Yuan (as San He Chun) opened in 1906 in a brick-and-wood building on Baoshan Street, and the flagship/总店 is listed at 宝善街195号; rename to Jian Xin Yuan 1952 or 1956 after joint ownership. Continuity of the exact 195 shop front back to 1906 is asserted by listings, not verified by an official record; no day found. Estimated: 1906 is a best estimate and 1906-12-31 is used only as a period-end sorting date, not a confirmed opening day.[1]A Baoshan Street rice-noodle shop serving crossing-the-bridge rice noodles, cold noodles and Yunnan snacks.
