It's too hot in summer, is it suitable to go to Hong Kong and Macao?

If it's mainly for fun, I suggest you come to June now, or don't come in July and August after 10. Not to mention exposure, there may be typhoon weather; It's not a big problem to travel alone, so don't join the group. Hong Kong and Macao are actually very small, and the road signs are clear. Do more homework online, and ask for directions when you arrive. Hotels can be booked on Taobao or Ctrip. Note that the hotel booked on Ctrip is settled in Hong Kong dollars, which is not more expensive than Taobao, and it is relatively guaranteed. It is also not recommended to live in Shenzhen at night. It is easy to come once.
