Are Yan's parents divorced?

Yan is a native of China. He is from Chongqing, but he was born in Guangzhou. Then his parents divorced when he was in primary school. His father immigrated to Canada, but he has been in China with his mother. Although his father has custody of him, he only went to Canada for a few months and then came back. He also has a half sister. Therefore, Yan is not a bastard.
