A consultant has three abilities: book knowledge, practical knowledge and insight. Book knowledge can be a doctoral professor and practical knowledge can be an entrepreneur, but how much a person can do depends on his knowledge. The biggest advantage of our consultants is that they can increase their knowledge. What is knowledge? It is what you see and pass by. It can be said that consultants can increase their knowledge more than the average person. Most people can only contact entrepreneurs after working in enterprises for many years, and can only contact government officials after working in the government for many years, but consultants often contact entrepreneurs and various government officials directly as soon as they start a project.
