it's the same door, and it's opened by a family.

Lu Gaojian was founded by Lu Bugao, a native of Outang, Wuxi, during the Tongzhi period of the Qing Dynasty. The two sons of the Lu family were named Lu Gaojian and Lu Gaojian, so they were used as the name of the store.

The earliest shop for recommending Lu manuscripts was opened in Wuxi today's Gongyun Bridge. Later, Lu manuscripts, the eldest son, went to Suzhou to open a branch in Suzhou with his aunt, which led to the recommendation of Lu manuscripts in Suzhou. Later, because of the appearance of a cottage shop in Wuxi city with the banner of landing manuscript recommendation, Wuxi Landmanuscript recommendation changed its name to "Real Landmanuscript Recommendation", which has been used ever since.
