The "Nine Obstacles" is the general name of the popular banquets in Guangdong Province, especially in the Pearl River Delta region. "Gui" was originally a round vessel for holding millet in ancient sacrifices. It is square or round in shape and made of wood, bamboo, pottery and copper. At first, it was an ancient aristocratic food container or sacrificial vessel, and later it gradually spread to the people. Every dish in Jiudaogui uses the best materials, but there is no beef, because cows can help farmers plow the fields. Hakkas call the nine bamboo poles nine sub-plates, which means "nine sub-plates join the company" and "long time". "Nine baskets" means a big banquet. There are nine baskets full of vegetables and food. In ancient times, it was often said that "two", "four" and "eight" were even numbers. Only Guangzhou, Hong Kong and Macao are used to calling the feast "Nine Big Ones". The banquet is called "Nine Big Guis" because adding the word "Big" between "Nine" and "Gui" is not only full of words, but also contains extremely rich and grand significance; Moreover, the ancients said that "at the beginning of creation, nine things competed." "Nine things", namely, wind, cloud, thunder, rain, sea, fire, water, earth and sky, are the things that "contend" at the beginning of creation, and they are the most important of all things, with their unique meanings. According to the excavation of an ancient tomb in the early Eastern Han Dynasty in Jinben Town, Sanshui County, Guangdong Province (now Jinben Community, Southwest Street, Sanshui District, Foshan City, Guangdong Province), what Cantonese call "Gui" is a "big bowl" that can hold five to six kilograms of rice. If people eat today, they can fill "nine big baskets" for 100 people to enjoy. It can be seen that the "Nine Obstacles" do their best to boast about their rich meals and high-standard banquets.
