That figures. China (Bejing) is 7 hours ahead of german time, yet I've noticed that my Tmall contacts are replying to messages when it is really late at night for them, sometimes excusing themselves that they have dinner right now. On 11.11 many are on duty for 24 hours.

Off topic, but in contrast to americans, german people are often frowning and complaining a lot - even though we really don't have much cause, in comparison. Friendliness and positivity are some of the things I really appreciate about the USA. Treasure it!
