Does anyone know my brother's couplets?

There is a couplet hanging on the front of Leslie Cheung's living room, which reads, "There are bamboo people who are not vulgar, and there is no orchid room to smell." The author is unknown, the textual research is unsuccessful, and expert advice is needed. It is reported that this couplet was written by Li Shan, a calligrapher in the Qing Dynasty. Shan Li and Zheng Banqiao are equally famous and both are "Yangzhou Eight Eccentrics". His poems, books and paintings are now treasures in the collection world. Judging from the style of calligraphy, it seems that this painting was not written by Shan Li.
