I don’t know what the questioner is thinking.

r First of all, the United States, like China, belongs to the northern hemisphere, with spring, summer, autumn and winter, which are basically the same.

r ①Depending on the seasonal situation, clothing changes according to the season, and they are all selling well. Americans like outdoor activities very much, so except for winter, spring and summer are basically outdoor shoes, clothing, and sports are selling well, but in summer, people wear less clothes, such as hair removal devices, sunscreen, and slippers.

r ②Analyze based on festivals, for example, Halloween must be related to Halloween products. Sell well, so Christmas is not a problem.

r ③According to Amazon’s color data feedback, it’s the same. Americans like high cost performance, and they don’t have much money, hahahahahaha

r ④According to Amazon’s category suggestions

r Mobile phone accessories: 82039731 types of products

r Home and kitchen supplies: 64274875 types of products

r Shoes, clothing and jewelry: 33422437 product types

r Electronic products: 31604887 product types

r Sports and outdoor products: 23997293 product types

r I hope my thinking is helpful to you. I didn’t tell you what’s selling well, hahahaha
