Some experts have pointed out that there is a simple way to judge the authenticity of famous white wines: famous white wines that are ridiculously low in price must be fake, and any customized wines that are sold outside under the banner of a certain famous white wine are fake. If you buy from formal channels, you can buy really good wine. These channels are regular supermarkets or hypermarkets; second, the flagship store authorized by the famous liquor brand; and third, the official website of the famous liquor company. Which of the following, if true, would most question the expert's point of view? ['Some hypermarkets do not strictly control the entry of goods, and the sale of counterfeit and shoddy products often occurs.', "There are many cases of online fraud, and the liquor sold by counterfeit famous liquor companies' official websites must be fake.", 'A TV promotion host claimed that although the famous liquor they sold was only half the market price, it was definitely not fake.', 'Custom wine produced by a premium liquor company is only used for internal reception, but it is true.']
