Day light saving time has begun. “Fall behind” that means everyone set the clock one hour behind in the autumn. There were 15 hours behind Hong Kong time. Now are 16. The sky turns dark by 4pm. And it’s foggy too. It’s really depressing. Watch out for the “winter blue” which is very common here in the United State. How do you prevent that happen? Spent more time with people you like or do things you like. Such as play with your children, pets, see your friends (the ones who are positive), watch a comedy or even wash your car (detailedly).
