I want to go to Beijing for a week or so in mid-May. What kind of clothes suit me? Do you want to take an umbrella to prevent ultraviolet rays? thank you

Wearing long-sleeved casual clothes, or wearing a T-shirt inside and a thin coat outside, Beijing will still be cold in the morning and evening of May, and the temperature will rise from noon to afternoon, more than 20 degrees! Beijing is quite sunny in May, because it is in the growing period of plants. You need an umbrella and sunscreen to prevent ultraviolet rays!
