I plan to travel all the way from Nanjing to Beijing in the summer vacation, and then go to Sichuan and Sichuan. Any good suggestions?

You must visit the Sun Yat-sen Mausoleum in Nanjing. Sun Yat-sen Mausoleum is located in Nanjing Zhongshan Scenic Area, at the southern foot of Zijinshan Mountain, and there are Ming Mausoleum and Linggu Temple nearby. Sun Yat-sen's Mausoleum is the mausoleum of Sun Yat-sen. The whole building complex is built on the mountain and arranged from south to north along a central axis. The whole cemetery is in the shape of "alarm bell" and is known as "the first mausoleum in China's modern architectural history". How about the Palace Museum, Tiananmen Square and Zuiguangwu Mountain in Beijing?

Nuoshui River Scenic Area covers an area of about 1.70 square kilometers, with karst landform as the main feature and large underground caves. The main caves include Zhongfeng Cave, Lion Cave, Loulou Cave, Longhu Cave and Songjia Cave.

The main peak of Guangwu Mountain is 2507 meters above sea level, which is named after being shrouded in fog all the year round. Guangwu Mountain Scenic Area consists of five major areas: Taoyuan, Shenmen, Xiaowuxia, Daba and Shibuya Beach, among which Taoyuan is the core scenic area. There are peaks, caves, mountain springs, forests and other landscapes in Guangwu Mountain Scenic Area, and the most distinctive is the red leaves in autumn.

There are also some historical and cultural relics of the Three Kingdoms period in Guangwu Mountain-Nuoshui River Scenic Area.
