"Buying a stock is buying a business." Concentrates only within his circle of competence, then holds nearly forever. Emphasizes integrity, equanimity, and that a stop-doing list beats a to-do list.
Founder of Subor and BBK, and the man behind the OPPO and vivo phone brands. After moving to the U.S. in 2001 he became a full-time investor through H&H International Investment. A devoted student of Buffett, he brought value investing wholesale into the Chinese context and, posting on Xueqiu as 大道无形我有名，shaped a generation of Chinese investors.
U.S. holdings are disclosed via H&H International Investment's 13F (≈45-day lag; auto-refreshed here). Large HK stakes (e.g. the May-2026 Pop Mart filing at 5.69%) surface via HKEX disclosure of interests; A-shares (Moutai) and his Xueqiu posts are outside the 13F and curated manually. His reasoning is on Xueqiu under 大道无形我有名。

In their own words
Do the right things, then do things right. The stop-doing list comes first.
Buying a stock is buying a business — its discounted future cash flow. The rest is noise.
If you don't understand it, don't do it. You'll only ever understand a few — and that's enough.
