There are a lot of small companies, including many US companies, where officers have lent money to the company at early stages.
However, I have an additional level of concern when this happens with a small Chinese company, as I think many of them still operate as though they were private family companies and not public entities. There is not a clear and consistently applied distinction between "company" cash and personal cash.
Other things equal I would prefer not to see loans from insiders, especially in Chinese companies.
