Su Huai, of course, did not treat Zhang Dayi unfairly or reprimand her harshly.
He did have the sincerity for cooperation.
Many people understand cooperation as "What conditions you offer me, I'll give you the same in return"; this is not cooperation, this is a job.
Workers should get paid for the effort they put in at work, don't talk to me about dreams, the future, or the big picture.
But cooperation won't work like that; there are too many things in a partnership that can't be quantified. If you haggle over every detail, nothing will ever get done.
So, the hardest part of cooperation is to let each other recognize the value of the other, then we can talk about distribution.
Each other, implies mutual valuation.
There's nothing much to talk about regarding Xingyu's fixed assets; the numbers are there, so it's mainly about getting Zhang Dayi to acknowledge the valuation of the intangible assets.
And of these intangible assets, Su Huai himself is the hardest to assess.
