如果要我理解的话，我只能理解到四季的季节。我喜欢春天去爬山，夏天去游泳，秋天去旅游，冬天过年。对我来说，春夏秋冬就是我的生活，我的生命。

It is really hard to guess the meaning of the she. We chinese seldom express our thoughts like this. Maybe the "他们“ in the context helps us to understand the meaning. If "他们” were her families, maybe she was expressing that she prefer the freedom than the familytie in the family.

Ich glaube,sie möchte nur äußern,dass sie die vier Jahreszaiten mag.

i dont think it was so simple as a net alias, because lateron she asked me if i also like 春夏秋冬. sorry i forgot to mention that as well... all in all i got somehow the feeling (during the conversation) that 春夏秋冬 had an idiomatic meaning, which none of my dictionaries (and google) did not reveal...

It's funny making so much misunderstanding. Actually it was very simple: here 春夏秋冬 was just a net alias of a net user.
