How to evaluate Ma Weidou's wealth?

he is far-sighted and has a unique personality (he may be a little lonely in his youth). He is not far from following the crowd and likes to innovate. For example, he used to like photography, but one day when he went to a certain place and saw a person with a camera on his back, he resolutely abandoned his hobby. He is a clever man and likes to be ahead of the times. Being a writer (literature began to wake up in his youth), being an editor, drilling antiques and running the media are all in the forefront of the times. Therefore, he is full of spirit, rich in cultural background, knowledgeable, smart and willing to work, and he is not rich, which is unreasonable.
