This should be said from the following points: First of all, in terms of the scope of communication, Go is wider than chess, which is certain. I think the reason why chess is worse than Go is related to sponsors. The sponsor sponsors Go because it has a high international influence. This may be the corporate philosophy of the sponsor. Think about why a sponsor wants to sponsor in order to improve the influence of his company. Go has these requirements. Chess is just the opposite, that is, its spread is only in China, and sponsors can't be interested, which also leads to the higher bonus of Go than chess. From the situation of playing chess, Go often appears in hotels, hotels and other high-end places, and chess often appears in small places such as homes and stalls. So chess gives people a casual feeling, unlike Go, which gives people a solemn feeling. These factors indirectly affect the sponsors' impression of chess, which leads to more sponsors of Go than sponsors of chess, and also makes the bonus of chess very small. This is my opinion, and I hope to get everyone's approval.
