Leaving the popular Nanluogu Alley and walking into the Houyuan'en Temple Hutong, you will find a very different and peaceful world. In this alley lies the former residence of Mao Dun, one of China's greatest writers and social activists. He spent his last few years here and left us many touching stories. There is also a special book store that was rebuilt from a traditional quadrangle dwelling, with a poetry theme. CGTN's Zhu Zhu takes you on a journey into this special hutong.
