That is totally wrong

I came here when I was 28 and I get along with ABC's very well. In fact I was a leader in my local ABC group in organizing activities. They eat Chinese food, speak Chinese (dialects such as Cantonese too) with their parents or fellow friends. They celebrate Chinese New Year, etc. Chinese culture is not lost in ABC's. Only in places where there are just one or 2 families of Chinese, ABC's Chinese culture influence is diminished. If there is a group of significant number, culture will perpetuate.
