I have been trying to find a dear friend in Chongqing, China. Her name is Dr. Xiaojia Guo. She works at The Center for Disease Control in Yuzhong District. I tried to contact that facility many times but I had no luck getting through. I even sent a mail but the mail was returned. Please, if anyone out there can help me out in reaching her, I would greatly appreciate it!!!!! Thank you so much.
