Besides, not everyone likes to drink China tea. In fact, almost all of them drink teabags! Send them loose tea, some don't know how to do it at all!
Send tea to my roommate, and buy a teapot with a filter to drink. Some westerners only accept black tea and are not used to the taste of green tea (especially Rizhao Qing)
You can also buy silk clothes to send. (Buy a large size)
