Topic3 Has "Chinese dama" been stigmatized?

Since 2013, the word "Chinese dama" has rushed into public attention. All of a sudden the word appears frequently in mass media. We see them dancing to loud music at squares home and abroad; we see them in expensive shopping malls and also in community open markets.
