Thank you all! many thanks:)

It's not tacky perhaps plain. There an English expression, "plain Jane".

Your English name is very common, but it does not sound tacky at all. While some people in English-speaking cultures think that it is important to have a unique name, the majority of people choose established names for their children. I know that it is very common for Chinese people to choose English names for dealing with foreigners who do not speak Chinese. In my opinion, it's best to either use your Chinese name (and expect that people will not know how to pronounce it correctly), or use a very common European name. Jane is a perfectly good name. While many people in our culture know what our own names mean, English naming is quite different from naming in China, as we don't usually know what each other's names mean. Jane is a name that came to English through a long list of other languages, ultimately originating in Hebrew. Like most originally Hebrew names in English, it has a religious meaning: 'God is merciful.' However, choosing this name will not make people assume anything about your religious beliefs. Most parents probably do not even think about the religious meaning of this particular name when they give it to their daughters, as the name is so common. Is the rhyme that you're asking about 'plain Jane'?

Jane \j(a)-ne\ as a girl's name is pronounced jayn. It is of Hebrew origin, and the meaning of Jane is "God is gracious." You know the famous British novelist, Jane Austen? Her novels are still popular even today.
