How to evaluate Ma Weidou's wealth?

He is far-sighted and has a unique personality (he may be a little lonely when he was young). He is not far from conformity and likes to innovate. For example, he used to like photography, but one day he went to a certain place and saw a man carrying a camera, so he resolutely gave up this hobby. He is a clever man and likes to be ahead of the times. Being a writer (literature began to awaken in youth), being an editor, drilling antiques and running the media are all in the forefront of the times. Therefore, he is full of energy, rich in cultural background, knowledgeable, smart and willing to work, and he is not rich, which is unreasonable.
