There must be no coffee shop, but there must be coffee introduced to China. Coffee originated in Africa and was later introduced to Europe through Arabia. Although the Arab merchant ships at that time had no trade with the Ming Dynasty, they did have business contacts. So there should be coffee along the coast. Because there was already opium in the coastal areas at that time, sailors in the coastal areas would also eat opium from overseas businessmen to alleviate the fatigue after making foreigners. But most of them were taken orally, because the method of smoking had not been invented at that time, and most of the sailors along the coast of China took it orally. For this reason, many people can't stand the smell of opium. Therefore, although the Ming dynasty was introduced, it was not as widely spread as the Qing dynasty. In the Ming dynasty at that time, there were only two kinds of people who ate opium. First of all, sailors and businessmen along the coast, because they have direct contact with opium. The other is wealthy businessmen and some nobles. Later generations discovered the ingredients of opium in the bodies of the Ming emperors when excavating the Ming tombs. It shows that trade was still very smooth at that time, opium was introduced, so coffee should also be introduced. It's just that their situation is similar to opium, and many people are not used to the taste, so there is no large-scale promotion.
