(ni hao, hello, guten tag!)
Let me comment on the language question: I would like to switch between posting in German and English. German regular, English while traveling. Then my friends in other parts of the world can read it too (and comment if they like to).
BUT: That does not mean that everybody has to comment in English. You are all very welcome to express your thoughts in German! Will that be a suitable solution? I hope so …
(xie xie, thank you, danke sehr!)
