On the one hand, because of the limited stock of Maotai puree and all kinds of artificial hype, Maotai has become a luxury national wine that ordinary people can't reach. The appointment of Maotai's self-operated store is open on time. If you don't make an appointment at the specified time, you won't succeed. Maotai has a small quantity every day and can be reserved twice a day. The probability of unsuccessful reservation is too low. I also made an appointment for more than a month without success.
