7 degrees. Do you want to wear long pants?

It's just right to wear warm pants at seven degrees, because it's already very cold at seven degrees, so it's impossible to wear only a pair of long pants, especially when it's cold to go to work in the morning and get off work at night.

Besides, students should pay more attention to keep warm when they go to school. Wear not only warm pants, but also cotton pants. Don't let their children catch cold.
