About this data
Figures are parsed from Chen Bihua's Form 4 filings on SEC EDGAR (CIK 1599214) and cover open-market purchases (transaction code P) — grants, option exercises, and sales are excluded, which is why totals here can differ from raw filing counts. Every row links to its source document.
