Generally, it is spot sales, wholesale and other work content. And it may also be the customer's development or maintenance work, and the line will be the best. I think any industry can be a success, but at present, the sales model and profit model of agricultural products are relatively simple, and domestic and international agricultural products are rapidly converging with international and domestic futures, so it is impossible for spot industries to make money. Of course, if the product has rich selling points or some bright spots, there is still much to be done. thank you
