According to food magazine Lucky Peach ,Cantonese dim sum culture began in tearooms in the latter half of the 19th century in the port city of Guangzhou, the capital of Guangdong, after opium dens were banned throughout the country. Silk Road travelers and traders would take breaks in tea houses for a dim sum meal. As they continued to travel, the practice continued to spread and gained popularity throughout the region, especially in Hong Kong. Nowadays, dim sum can include dishes and traditions adopted from other parts of China. But by and large, the culinary form remains the same as ever.
