Zhang Qing

Zhang Qing -- where are you?  You were in New York in 1994, then you disappeared.  Well, love to hear from you if you are still out and about.  You son must be 20+ now.  How are you doing.
P.S 
Zhang Qing graduated from Shanghai Institute of Foreign Trade in 1983.  Then she worked in HangZhou for a couple of years.  She came to New York in 1989 or 1990.  Any help/lead will be highly appreciated.
