Under the premise that a preliminary cooperation intention has been reached, it is meaningless to fuss over such trivial matters.
Han Mengying was worried that Community 17 might play tricks, but she couldn't figure out any specific possibilities. Since that's the case, as long as the key personnel for this plan are restricted, it can still have some effect.
She certainly knew that Qin Yao was practically Lin Sizhi's puppet and would definitely carry out Community 17's group decisions seriously. But as the core person of this plan, if 'Finance' doesn't have a strong mind and psychological quality, flaws are likely to emerge when executing complex plans.
It's much safer to have Qin Yao act as the Finance than to have Lin Sizhi do it himself.
But since Han Mengying specified Community 17's 'Finance,' she certainly couldn't serve as the Finance of Community 4 herself.
