The most worthwhile scenic spot in Nanjing is the Jiangning Weaving Museum (15 yuan for students and 30 yuan for adults). Cao Xueqin Memorial Hall in Oolongtan Park is not open very often. There are too few elements in Red Mansion Art and Literature Garden in Zhongshan Mausoleum Scenic Area. Jiangning Weaving Museum is a modern museum built by Mr. Wu Liangfu on the old site of Jiangning Weaving. Mr. Wu combines classical gardens with modern architecture with the design concepts of "walnut pattern" and "bonsai pattern", forms the overall framework of gardens with landscape pattern, surrounds Lake islands with green water to metaphorize Egret Island, and matches with western gardens and garden-following gardens. In the Jiangning Museum, we can not only have a deep understanding of Cao Xueqin's background, but also the different versions of the Dream of Red Mansions. We can also see the production history of Yunjin, a historic activity of Jiangning Weaving Bureau under Jiangning Weaving Bureau. It's really enjoyable to see Yunjin Qipao weaving in Jiangning, but there was a tea house in Jiangning Weaving Museum, but it closed on the day we went there.
