First, NGO itself is a non-governmental organization, and there is no law to stipulate the rights and obligations of organizers. It all depends on personal qualities. Therefore, when NGOs were founded, there was no effective way to restrain individual behavior, and they could only rely on morality to restrain themselves.
Second, China does not explicitly encourage the establishment of NGOs, so it is very difficult to establish NGOs in China.
Third, NGOs have limitations in management, training local staff, project replication ability and coordination with government services at an appropriate level.
Hehe, that's all I know. I think the most important thing is that the belief and quality of managers are the biggest limitations of NGOs.
