After looking into it, this female salesperson was probably manipulated by a performance-obsessed corporate culture, and then used the company's halo to manipulate colleagues and clients, under the pretext of "helping the company boost performance" and "diverting marketing expenses," to borrow large sums of money, promising high interest rates (1%-2% daily interest, over 300% annualized), using new money to pay off old debts, ultimately leading to a collapse of the funding chain.

She didn't embezzle the boss's money, nor did she run away immediately after getting the money, but instead, in order to get better treatment and higher status from the company, she deceived those who trusted her into giving money to Taikang, building a false image for the company, and eventually couldn't repay the debt.
After failing to repay, she was also reluctant to resign, and instead, she stopped pretending in front of clients, directly admitting she couldn't repay the money and could only deceive others into lending her money, which led to clients reporting to the police.
From the boss's perspective, Ren Xiaomin is actually neither smart nor honest, but sufficiently "loyal," very dependent on the rewards and punishments from superiors; she contributed to the company's performance but bears responsibility when things go wrong.
Those who hold her in high regard among acquaintances are doomed to misfortune; she would rather betray acquaintances than fail to support herself.
Because she values her status within the group more than money or connections, this kind of person is a typical workplace traitor.
