A company that accepts investment earlier will own a smaller portion of it by the time it goes public.
Comparing wealth with "nations' worth" investment institutions, Yan Yan's existing assets were truly insignificant.
But if a company doesn't lack money during its development, it isn't necessary to go public.
For private enterprises, firstly, they don't need to disclose their performance; secondly, they aren't subject to various departmental supervisions; and thirdly, they don't have to explain to investors where exactly the money is spent. In short, if there's no need for "high-speed" capital for expansion, staying private has many advantages.
Take Y·Y now for example, completely disregarding money, only opening for half a month each, such a waste of rent and resources—should this get included in a public company's financial report, they'd surely be criticized to death by investors and shareholders.
If Y·Y went public, it definitely couldn't continue to be capricious.
