1. Observe commodity packaging: observe whether the logo, trademark and packaging of the commodity are consistent with the genuine product from the outer packaging of the commodity.

2. Look at the price of goods: If the price of an overseas commodity purchased in the world is significantly lower than that of other channels, it is very likely to be a fake or a defective product with poor quality. 3. Check the product evaluation: When checking the product evaluation, we should not only look at the positive rate, but also look at the content of bad reviews, and see what problems consumers have reflected, such as whether it is easy to damage.

4. Verify the source of goods: When purchasing overseas goods, it is best to choose a reputable merchant. You can check the qualification certification, transaction history and other information of the merchant, or directly go to the corresponding official website for inquiry.
