★The original meaning is to wish the next meeting. As Chinese have been admiring the western accomplishment since China's reform and opening, it is popular for a long time to throw out several English words in their speaking to show themselves a little bit western. Therefore the youth also say goodbye with“拜拜” to each other. Lots of foreigners think it is ok to just say bye-bye without “再见” as “拜拜” pronounces same as bye-bye. The fact is that things change now. As nowadays Chinese regard it is very foolish to speak out several English words in the talking so it is literate to use “再见”instead of “拜拜”.
