"苏州是桥梁的发源地"，正如一位名叫罗元粞的“古桥保护志愿者”所说的,因为他相信他关于苏州的古桥的画将有助于保护城市的古老建筑。《念桥边》是一部简短的实验纪录片，主要探讨苏州市三座历史上非常重要的桥梁，主要从美学、结构、功能和氛围来展示的；三座古桥分别是：宝带桥、枫桥、吴门桥，并且也与现代建造在古代设计基础上的桥梁做对比。这部电影唯一的人文主题是一位名叫罗元粞“志愿者”，一个70岁的有趣的老人,至今已经画了苏州100座古桥。

“Suzhou Is the birthplace of bridges” as says Luo Yuanxi, a “volunteer” - as he call himself – because he believes his drawings of the ancient bridges in Suzhou will help protect the ancient architecture of the city. “Maple at Night” is a short experimental documentary that mainly explores the aesthetic, structure, function and atmosphere of three historically important bridges in the city of Suzhou: Baodai Bridge, Maple Bridge, Wumen Bridge and contrasts them with the modern bridges that are built based on the ancient design. The only human subject of the film is a “volunteer” named Luo Yuanxi, an eccentric 70-years old man who has drawn 100 ancient bridges of Suzhou so far.
