Thanks for all of reply.
I know Yinan Wang, I've met. He is a PhD on chemistry, he studied abroad to Canada in 2008. After finished PhD, he worked in a Japan lab as a researcher. Then worked in Canada again. For now he works in UCSD(
University of California San Diego) as a researcher too. He met Jie Song in high school, they were desk mates. Their high school classmates said that they're 'soul mates'.
They got married last year even without a wedding because both of them were busy on their work. Yinan Wang planned working in China later to stay with Jie Song.
About Jie Song it's from my memory.
In 2008 I got to Hangzhou Shidai Primary School. Also Jie Song got a job here as a English teacher. Our school start English courses from grade 1 experimentally while other school start it in grade 3. It's a challenge to teach 8 years old students English. But Song rose to that challenge as a new teacher. She just got 'Professional Eight Level of English', the highest English level in China. She taught us 4 yrs. I can never forget his smile with kindness and confidence. She often call us answering questions and praise us. We keep contact with her even a long time after we graduated. We just visited her at the start of this summer vacation.......
