Duan Yongping
Duan Yongping appears in EP90 从美加墨世界杯看懂期权—华尔街的终极武器 as a modern investor example for Option Selling Discipline. The episode says he used put selling to enter Pop Mart at a lower effective cost and call selling on Nvidia to collect premium while accepting sale above a chosen price.
The source uses Duan to connect options back to value-investing intent: the strategy is only coherent when the investor knows the asset, has the balance-sheet capacity to accept assignment, and is genuinely willing to buy or sell at the defined price.
E44 李晓波对话孟岩：这次，就这样吧？ adds Duan as the reference point for Benfen / 本分, plainness, and doing the right thing without over-performing for others. Li Xiaobo / 李晓波 and Meng Yan / 孟岩 use him to discuss whether founder culture can transmit method-level principles such as ordinary mind, stopping when wrong, and knowing what should be done.
