You must check out the Jiangsu Garden Expo Park.

Jiangsu Garden Expo Park is a check-in spot that integrates classic global cultural and creative elements. It has 2.54 million square meters of garden landscape, 310,000 square meters of characteristic buildings and 24.3 kilometers of municipal rail transit. Relying on the terrain of industrial relics/mining remains, it has created four unique and exquisite flower valleys: Cliff Flower Valley, Time Art Valley, Su Yunhui Valley, and Yunchi Dream Valley. The unique landscape of the exquisite urban garden incorporates a variety of elements such as small trains, cable cars, delicious food, internet celebrity exhibition halls, botanical gardens, etc., becoming an ultra-large ecological, cultural and tourism complex in Nanjing. We selectively visited several attractions. Time Art Valley: The Pioneer Bookstore has a very distinctive design aesthetic of geometry and literature. The white spiral staircase and cylindrical book room give you a different feeling. It has been rated as one of the "Top Ten Most Beautiful Bookstores in the World" by many newspapers and has become a must-visit place for Internet celebrities. There is also the warm Coca-Cola Museum, Time Post Office, and so on. Suyunhui Valley: A condensed landscape named after the thirteen gardens of Jiangsu Province, with pavilions, flower and bird ponds, and winding paths. Each garden reflects the unique style of a city. We admired nine gardens, including Nanjing Garden, Suzhou Garden, Yangzhou Garden, Wuxi Garden, Yancheng Garden and Xuzhou Garden, and had lunch at Yechun Tea House. Cliff Observation Deck. After exiting the pumice underground palace, take two long escalators to the highest observation deck, where you can enjoy the beautiful scenery. In particular, there is a hotel built on the cliff of the mining valley - Huachu Village, hidden in the botanical garden, which is magical! Yunchi Menggu, which is dominated by a breathtaking underwater botanical garden, is a perfect fusion of scenic spots and mountains. It is a feast for the eyes!
