Carrying an umbrella in a sunny day

Something strange I noticed when I arrived Taiwan is that many girls carry an umbrella in the sun.
First I was like, is it going to rain ? Well, no it's not. In Taiwan, people are obsessed with white skin color not like in Europe where girls rather like to have a tan.

I found an intreseting post from a user which explains why they are obsessed with white skin color:

Chinese woman equate sun exposure to being lower class. Only farmers in China would get sun when they were working in the fields. So the upper class Chinese woman dont allow any sun on their face or body and thus walk around with umbrellas when it is sunny out.

They even have skin care products which focus on whitening the skin
