Is it necessary to wear woolen pants or warm pants in this weather in Beijing?

When the weather is cold, people will feel very cold before their pores shrink.

When it's colder, you and your pores are used to it, so you may not feel warm if you wear as much as you do now.

So wear it when it's cold, no matter what happens later!

No matter what happens, meet the needs now and talk about it later.
