Question

is this sentence right?
Bei Schnee ist es in Beijing sehr Schön, bei Regen auch. 
Bei or Beim should be used?

Answer

"Bei" is correct ... When you doing something(  in action )  like swimming for example .. You use : Beim Schwimmen ,  Beim Sport....

Answer

You normally use "bei" - "beim" is used when it's written before an indirect object. Btw: adjectives are written with a lowercase letter at the beginning and Beijing is called "Peking" in German.

Answer

"Bei" is fine. (And it should be "schön" instead of "Schön".)
