To find products with good sales, you can consider the following methods:

1. Search on e-commerce platforms: On large e-commerce platforms such as Taobao, JD.com, and Tmall, there are generally sales rankings or hot-selling lists. You can browse these lists directly to find products with high sales. In addition, you can search for keywords and sort by sales to find popular products.

2. Refer to user reviews and comments: Read other users' reviews and comments on products to understand the actual use experience and product quality. If a product has a lot of positive reviews and high scores, it usually means that it also has good sales.

3. Consult professionals or industry experts: You can consult professionals or experts in related industries to find out which products sell well in the market. These professionals usually have a deeper understanding of the market and relevant data.

4. Search market research data: There are many market research institutions that publish data reports on the sales and market share of products in various industries. You can search for relevant reports to understand the performance of specific products in the market.

It should be noted that products with good sales may not necessarily suit your personal needs or be cost-effective products, so when choosing to buy, you should also consider the product's functions, cost-effectiveness, and personal needs and preferences.
