At first, the sellers of idle fish were mostly individuals, and the trading motive was to sell idle items. Nowadays, a large number of professional sellers of idle fish have poured in and become very commercialized. Experienced buyers will prefer individual sellers, which are relatively reliable and cost-effective. So how to distinguish professional sellers from ordinary sellers?

1. Look at the number of "I want". For the idleness of individual sellers, I want a product with more than 20 people. Ordinary buyers usually sell their products when they feel fit, and no one will buy them and hang them all the time. Those "I want" dozens or even hundreds of idle items are probably drainage stickers for professional buyers.

2. Look at the personal description. Individual sellers are usually more casual when describing products. They will only briefly introduce the products and explain the old and new degree, and most of the pictures are real pictures, and they will not deliberately pay attention to picture typesetting. Professional sellers usually describe the products in detail, which needs to be expressed as official. The same product has complete models and beautiful pictures, most of which are commercial pictures with unified style.

3. Look at the product category. Individual sellers usually sell various products, including various categories; Professional buyers generally specialize in one category, and the products in the same series have complete models and more inventory.

4. Look at the dynamics. In order to pretend to be individual buyers, some professional sellers regularly delete some goods from the homepage, and the dynamics are automatically generated by the system. The products on the shelves and the products sold are recorded. In the dynamic, they saw that the same product was sold several times, or it was put on the shelves as soon as it was removed. Most of them are professional sellers.
