How to spend 4 days and 3 nights in Shenzhen?

Who says Shenzhen isn't worth visiting? How to enjoy a 4-day, 3-night trip in Shenzhen? Just got off the plane I was touched by the slogan 'Once you are here, you are a Shenzhener', Shenzhen really is a city with great inclusiveness, 'This Rongbian ribs were recommended by my Shenzhen friend, I didn't get to eat it after coming twice, but today I finally had it' The ribs have a slight milky flavor, and they are so delicious with rice On the second day, you can go to Shenzhen Bay Park, which is right out of the subway station, and it's free, with beautiful scenery. Just be aware that the weather might be a bit hot, so be prepared for sun protection I recommend trying the No. 79 fishing boat, the seafood is very fresh, but you need to go early, otherwise, there will be a lot of people in line On the third day, you can go to Upperhills to have fun, there is a shopping mall below, and there is a small town above, it's very beautiful for taking photos and checking in, and there are many stylish shops
