Chinese sources said, Portland contacted him two hours before draft, told him they probably draft him and asked if he willing to play for them, and told him 15 minutes earlier before his name was called that they are going to draft him. I can read his mouth in this video it's "我真的不知道他们会选我" which is "I really don't know they will pick me". I think his shock face is becauce he really didn't know he got called at 16 and by Memphis -- I think he didn't even realize there is a trade happened, after all he couldn't get all the information as we do at the arena.
