I'm tourism professionals, and the following are all designed by myself. If there is any coincidence, they are all the same. Judging from your question, it is estimated that you are leaving from Shenzhen.
D1: Depart from Shenzhen in the morning, see the fishermen in Zhuhai, and take the lovers' road. If you have more time, go to Shijingshan for lunch, eat seafood in Wan Chai, or go further to Hengqin for oysters, and go to Yuanming New Garden in the afternoon. During the Spring Festival, there will be flowers and drums of the Royal Temple Club. Stay in Haiquan Bay or Imperial Hot Springs at night (I'll give you two choices because there may be no room), and soak in hot springs at night.
D2: Play the Mystery Island Paradise. (When to get up, how long to play, customize it), just eat lunch in the garden (because you have to buy tickets when you come out). . If you don't go to the paradise, you can go to Jintai Temple (a big and beautiful temple), or you can all walk a little farther to the Yamen ancient fort in Xinhui (let the bullets fly, you can see it, there are several shots here, from the above two hot springs, you can get there in 2-3 minutes by car. ) If you don't go far, go back to Zhongshan City, and the five-star Sheraton/Shangri-La/Huahong is not very expensive during the Spring Festival.
D3: Take a walk in Zhan Garden, the best scenic spot in Zhongshan (personally), and have lunch at the nearby farmhouse restaurant, or go back to Taishan Xinghua Monopterus albus Rice opposite the south station (because you didn't go to Taishan, this is a branch), and you can go to Sun Yat-sen's former residence (in Beijing and Zhuhai) in the afternoon. Or leave early, you can go first on the first day), and then go to Lingnan Water Village. After all, Shenzhen is too big a city. I live in Humen at night, and there are several four or five stars on Humen Avenue.
D4: I will go to the naval battle museum in the morning, have lunch, and then go back to Guangming. I will go to bright farm to let the children milk and go back to downtown Shenzhen.
