I recommend the best route for a one-day tour in Shenzhen. Get up and have breakfast in the morning, then take a bus to Lianhuashan Park, overlooking the essence of Shenzhen city at the top of the mountain, take photos and punch cards in Shenzhen Library and Concert Hall after going down the mountain, and have a short rest. After the rest, go to Shenzhen Museum and learn about Shenzhen The history of ancient times and reform and opening up, and then take the subway to the convention and exhibition center for lunch. This is the place with the most shopping centers in Shenzhen, where you can enjoy yourself, such as Huang Ting Square, Central City, Zhuo Yue intown, Shopping Park and Liancheng Xintiandi. After 3-4 pm, take a bus to Shenzhen Bay Park. After having fun in Shenzhen Bay Park, go to Happy Coast for dinner, enjoy the night view, and then go back to the hotel. This kind of trip is very compact. I went to the famous scenic spots in Shenzhen, all of which were free. I saw the scenery of mountains and seas, and I experienced the modernization and prosperity of Shenzhen. I have friends who come here to take this route!
