China & The World Cultural Exchange 2003年第1期69卷 15-17页

作者： Zhang Jing photo by wu Wei

Located at the easternmost point of the famous Liulichang Street in Beijing is the Songtangzai Folk Sculpture Museum， privately run by owner Li Songtaog, who spent most of his life savings to renovate the simple twostory accommodation built during the Qing Dynasty. The outside of the museum doesn't look so different from the dozens of other quaint and quirky antique shops along the world-famous Liulichang Street. But inside,

一个普通的游客,当他走入博物馆去参观那些离他甚远的历史文物时,他很有可能是入芝兰之室而不觉其香,以为造访博物馆只是枯燥无味的游逛。而这个世界上有这样的一群人,他们希望人人都能分享探索博物馆的愉悦,尤其不愿意看到来者千里迢迢地赶来却空手而归。于是,他们成为了志愿者,主动地走近游客,分享他们的知识。虽然很多时候的都是面对相同的展品说大致相同的讲解词,但他们却感到一种心灵的富足。就这样,一个本应该出现在时尚地标的美女,静静地站到了故宫的宫殿里面。
