Ye Qing was talking about Liu Yuan. When Ye Qing first arrived in Shenchuan City and started working for Mu Qingrong's company, the first client he met was Liu Yuan.
Back then, Ye Qing secured the company's first business deal with a proposal. He later created several more proposals for Liu Yuan, which landed him several large contracts. Liu Yuan saw Ye Qing as a good friend and even paid most of the fees in advance to help. It was Liu Yuan's assistance that got Mu Qingrong's company through its toughest financial times.
When several companies joined forces to take down Mu Qingrong's company, Liu Yuan, a junior manager, went against his boss's wishes and supported them until the end without kicking them while they were down. Ye Qing recognized at that moment that Liu Yuan was a worthy associate.
