Every country has its own drinks, such as herbal tea in China, cola in the United States, Fanta in Germany, Crepis in Japan and Kvas in Russia. Since ancient times, Kvass, like vodka and bread, has always occupied a high position in the hearts of the Russian people.

Generally, disposable plastic cups are used, and about six or seven rubles can be drunk on the spot. The most expensive cup does not exceed 1 rubles, which is equivalent to less than 1 yuan RMB. You can also prepare your own big empty beverage bottles, such as coke and juice bottles, and sell them for 7-8 rubles a bottle, which will only cost you 67 yuan in RMB.
