Please come in from Hong Kong and Shenzhen to ask for directions.

Apart from the famous places you listed, I like Sha Tin City Plaza best, because it is closest to us and it is much more convenient to eat than Tsim Sha Tsui Causeway Bay. There are many brands in Hong Kong, and there are many stores in every place, just like there are at least five Broadway in a street in Mong Kok. So if you don't buy anything special, it is almost everywhere.

2. Go to Central, preferably during office hours, and you can see busy and fashionable office workers. It is said that Hong Kong's elites are all in Central, and you will gain something from their clothes. As for shopping, it's the same as anywhere else.

In fact, you can go anywhere. Holidays are full of people. There is a subway to Tsim Sha Tsui East at Futian or Luohu Port (the terminal was Hung Hom about 10 years ago), and there is a bus to Wanchai at Huanggang Port. Then you can change to the subway to go to Causeway Bay and other places, which is more convenient than taking the subway and always changing lines. As for transferring from Hung Hom to public transport, there are many cross-sea routes, such as 103, 1 14. But if you are not familiar with it, don't change trains.

Besides shopping, I think it's good to go to Victoria Harbour to see the night view.
