Oh my! Mr. Xu passed away just two months ago. Just now I saw a post on X, then immediately checked his Moments (朋友圈). Time really did stop on February 16th. He was super charming, extremely patient, and utterly candid and sincere. The in-person talk was especially beneficial. 😂😂😂😂😂😂😂😂😂 Forebears… such a pity!
