As for Xinjiekou, it is just a commercial center. All cities have them. There's nothing to see. There is also Yuhuatai, which is not suitable for Chinese New Year. Suggest going to the Spring Festival. In addition, Sun Yat-sen Mausoleum, Ming Mausoleum and Purple Mountain Observatory must avoid winter, and winter is in the mountains. It's very cold, and the scenery in winter is not good. Spring and autumn are fine, and summer is the best. In addition, there are many other scenic spots in Nanjing, such as Mochou Lake, Yanziji, Pearl Spring, Tangshan and Hongshan.
