First, check whether there is a trademark or brand name printed on the packaging box. There is an R in small font printed on the upper right corner or lower right corner. The letter R is the prefix of the English word REGISTER, which means "After registration", the quality of the product has been recognized by the company, and then it has the right to use this kind of packaging.

Second, you can check the name of the place of origin. If there is a mark on the back cover of the appliance that is made in the country of production (such as Made in Japan) or the region of production (Made in Hong Kong), it can be distinguished whether it is a locally made product or a product of a subsidiary. Some home appliances do not indicate the place of origin. You can ask the seller for the product instruction manual to check. Those products that have neither instructions nor certificates must not be purchased.

Thirdly, most foreign companies use their company names as their trademarks, and counterfeiters use such trademarks to deceive. In order to prevent being deceived, when purchasing, pay attention to which company is marked on the outer packaging or manual of the product to confirm the company's product.
