(We may still be a few years away from a real metaverse product, but it doesn't rule out us making money now. Many metaverse courses on the market are just for the popularization of concepts, but the perspective of this course is "present". From the perspective of making money, start contacting the Metaverse circle now, get on the car in Metaverse, and prepare for the real Metaverse products in the future, which has a cognitive first-mover advantage.)
