Yes, it's better not to drink Chinese tea at least 8 hours before go to sleep.

Impossible to comply! 8 hours!

In general, Chinese people only drink Chinese tea during the day, but some people also drink it at night. They drink a lot and have adapted, so they don't keep up at night

Still no sleep for the second night! I have to switch from Chinese tea to Earl Grey tea!

Oh oh oh! Some Tea has lots of caffeine!
