What necessities do you need to take to travel to Hangzhou?

Appropriate cash, one or two bank cards, mobile phones, cameras, when staying in hotels and homestays outside.

I suggest you bring a towel.

I didn't know you were in summer.

I still want to come to Hangzhou in winter. It is very cold in winter and the humidity is still relatively high, but there are few snowy days. I suggest that you bring more clothes to Hangzhou in winter, and bring some small warm items such as warm babies, earmuffs and gloves. The weather is hot in summer, and heatstroke prevention is particularly important. Sun protection and shading are very important, and anti-mosquito measures should also be done well. Moving a big box is the most important thing for you. PS: It is suggested that you should never travel to Hangzhou on legal holidays, because there are too many people.

I hope it will be helpful to you and I hope it will be adopted.
