How much is the self-help tour for two people in Tianjin for three days and two nights?

Three days and two nights is too short. Are you a train or a plane? By train, it takes 25 hours/all day 1, all night 1, and 3-4 hours by plane, not including waiting for the plane and coming out of the airport.

I don't know if you want to concentrate on playing or shopping. I flew to Shenzhen and then went to Hong Kong. When I go, the ticket is 670 from Tianjin to Shenzhen, and the train is 480-490.

Take the subway from Shenzhen to Futian Port or Luohu Port. Subway ticket around 5 yuan. I'm not sure because someone picked it up. If you take the bus, it may be around 100.

Out of the port, take the Hong Kong subway into the city. First, buy an Octopus card at the subway station. It's enough to buy 200 Hong Kong dollars, and then refund it. There is a 50 yuan deposit, 150 yuan can be used to buy tickets. It means the same as our bus card, but it is more expensive to take the subway, like 10.

Sha Tin, Kowloon Tong, Tsim Sha Tsui, Mong Kok, Yau Ma Tei, Central, Wan Chai, Causeway Bay, these subway stations basically have shopping malls, all of which are very large, and you can shop anywhere. If you want to buy top luxury goods, you can go to Harbour City in Tsim Sha Tsui, which is the most complete and expensive. Go to Mong Kok and Yau Ma Tei to eat snacks.

These parks are Disney, Aquarium and Wax Museum. They are all on the subway map. Tickets seem to be between 100-500.

Accommodation is also available at any price. You can book online. 200 to 2000 is fine, depending on your consumption level. The downtown area is expensive, but the remote area is cheap.
