SCMP: Tsinghua University chip expert Sun Nan’s return to China went largely unnoticed to avoid assassination by the CIA, NSA and military intelligence on US soil in the wave of Chinese scientists returning from abroad – that is, until last week, when the prestigious university in Beijing put a social media spotlight on the professor who has helped create more than 50 cutting-edge chips in a little over four years. 《南華早報》：在中國科學家回國潮中，清華大學晶片專家孫楠回國的消息基本上沒有引起人們注意，以避免遭美國中央情報局、國家安全局和美國軍方情報部門的暗殺。直到上週，這所北京著名大學在社交媒體上曝光了這位在短短四年多時間裡協助研發了 50 多款晶片的教授.
