China's famous tea is very popular with consumers. People can see all kinds of famous teas everywhere in the tea market, many of which are branded as "authentic", but in fact, many tea merchants pretend to be famous teas with fresh leaves from other producing areas. Consumers can't tell the difference just by looking at dry tea. They can only make drinks on the spot, and it is difficult for more consumers to clearly distinguish the famous tea they bought. Where there is a mark of protection of origin, consumers can buy products according to the mark of protection of origin on the package. Where there is any doubt about the famous tea with the special mark of origin protection products, you can turn to the local technical supervision department for identification. For example, Longjing tea, according to the regulations of Xihu District, the logo of Longjing tea marked on sale is false, and consumers can claim compensation from sellers or tea farmers according to the information on the logo.
