Analysis · TRSG · Technology
The CEO, Chairman, and Director resigned effective September 14, 2026, and the Board appointed his spouse, Liling Du, as Interim CEO effective September 18, 2026. This is the third senior executive departure in roughly a month — the CFO resigned effective September 4 and the CTO resigned effective October 9 — leaving the company with an interim leadership team drawn from within the founding family. The spouse appointment raises governance concerns about independence and succession planning at a time when the company is already dealing with previously disclosed related-party guarantee issues.
