Story Legend has it that after Qin Shi Huang unified the seven kingdoms, he set out to pacify the Hundred Yue in the Lingnan region. In 219 B.C., Emperor Qin Shi Huang appointed "Tu Suo" as the main general and "Zhao Tuo" as the vice general to lead an army of 500,000 to pacify Lingnan, and the army pushed forward to the area of Lingnan, which belongs to the monsoon climate zone of East Asia and has the climatic characteristics of tropical, subtropical monsoon and oceanic. The soldiers of the Central Plains are not adapted to the humid climate of the South, have been sick, the army combat effectiveness greatly reduced, repeated defeats, just when the generals are at their wits' end. Followed by the army doctor developed a dual-use porridge, with lotus seed, lily, saxifrage, Tsesi, bamboo, Chinese mountain, barley as raw materials, after processing into a paste to eat. After taking it, people felt calm and energetic, and the army fought bravely again. Zhao Tuo said with emotion, "Eating it clears the heat and replenishes the vital energy, and it can be called Qing Tonic Cooling. In order to ensure combat effectiveness, Zhao Tuo ordered his men to eat a bowl of Qing Tonic Liang every morning. After the Qin Dynasty fell, Zhao Tuo raised an army and annexed Guilin County and Xiang County, establishing the state of South Vietnam in the southern part of the country, and called himself "King of Wu of South Vietnam". He established his capital at Panyu, i.e. present-day Guangzhou City. He reigned for 71 years and was truly a "long-lived man".　Chinese medicinal cuisine has a long history and has been widely spread from the court to the people.

Origin and Sources As early as in the 1920s, Hainan has a Qingxianliang, then Qingxianliang is mainly some temporary stalls in the streets and alleys, there are individual small tea Qingxianliang halls have Qingxianliang sold. 40s, three or five coins can be purchased in a bowl of Qingxianliang. Unlike other counties, Haikou has more varieties of Qinglian. "Qingzanliang was once operated in the store," said Tang Renzhi, vice president of the Hainan Provincial Culinary Association, probably in 1953, when Haikou Second Catering Company (Cooperative Shop) has more than 10 stores under it, and a part of these stores "invited Qingzanliang to be operated in the store". ". Tang Renzhi said that at that time, the state-run units have labor insurance regulations, in the summer units should be issued to employees Qingxinliang, as a way to cool down the summer heat, so in May, June, July and August, the business Qingxinliang stores business is very good. Culture Haikou Qinglian is rich in raw materials, less than a dozen kinds, more than 20 kinds, mostly locally sourced, fresh and delicious.　Hainan Qingzheliang is different from the herbal tea in Guangdong, where if you are on fire, you mainly drink herbal tea to reduce the fire. But herbal tea is bitter and hard to drink. According to the Qingxinliang Chinese medicine said that although the herbal tea is to reduce the fire, but should not drink more. Guangxi Guilin, Nanning and other places also have Qingjianliang. Listen in those two places to go to school in Hainan students back to say, the most delicious, the most reminiscent of Hainan's clear complementary cold. It is understood that Guilin's cooler raw materials in the watermelon, pineapple, green beans, etc., these raw materials are placed in the refrigerator; and Hainan's cooler is not the same as the Guilin cooler is more like a "fruit mixed ice" that kind of thing, sweet. Nanning Qinglian compared to Hainan Qinglian is much simpler, with less ingredients, the flavor is also worse.　Compared with other provinces, Hainan Qingxinliang can not only reduce fire and sweet and refreshing. Provincial Culinary Association Secretary General Lin Junchun said, Hainan's Qingziliang, mainly based on the local climate, living habits, the use of summer cooling ingredients. General Qingzhengliang raw materials less than 10 kinds, more than 20 kinds, Haikou street and alley common Qingzhengliang ingredients are peanuts, red beans, mung beans, macaroni, fresh coconut, dates, watermelon, pineapple grains, quail eggs, cold powder block, pearl, barley, taro and so on.　In Hainan, Wanning, Qionghai and other cities and counties of Qingzhanliang is also very popular with local citizens. It is understood that the Qionghai cooler, the past raw materials with angelica, but now less used. At present, the most distinctive point of the Qionghai cooler is that it does not add ice, but with "fried ice" to match the cooler ingredients. People in Qionghai told reporters that this "fried ice" is coconut milk with sugar and then add milk, after the fire after stirring constantly. With "fried ice" blending out of the Qingxinliang melt in the mouth, eat smooth, delicate, a bit of ice cream flavor. "Compared with other cities and counties in our province, Haikou's Qinglian is different," said Lin Junchun, mainly because of Haikou's more varieties of Qinglian, but also more complete.　Qingxinliang queue under the coconut tree to eat Qingxinliang Hainan's Qingxinliang stalls are mostly located on the roadside, stallholders placed a small window, next to a thermal ice bucket, several sets of plastic chairs and wooden tables, plus Qingxinliang stalls in a small window full of plastic bowls, bowls were loaded with yellow, red, green and other raw materials. In this way, a stall will be recruited Qingxinliang to a group of customers. In Hainan, most of the stalls of each cooler have no "name", if where the cooler is delicious, the public mostly to the road name to recommend to friends. Live in Haikou, many people know that in Haikou, the clear cooler stalls more and more large when the number of Haikou Xinhua South Road, the "old" stalls. Early summer nights, and friends tired of shopping, or walk with the family, some people will come to Xinhua South Road Qingziliang stalls, point on a bowl of sweet and refreshing Qingziliang. However, those who eat here must be a bit patient, as they need to queue up to buy a license, then hand it to the waiter to be seated, and then wait for a while - because there are too many people coming here to eat Qingzanliang. However, when a bowl of ching chong liang with ingredients such as green beans, red beans, macaroni, quail eggs, red dates, coconut water and so on is served in front of you, you will feel that even the long wait is worth it because when you take a sip of fresh coconut water soaked in ice, and then bite into the sweet, icy, powdery and soft quail eggs, the refreshing feeling that goes straight to the bottom of your heart, and the coolness that penetrates right to the bottom of your heart, simply leaves you speechless. The coolness of the quail egg and the coolness of the quail egg will leave you speechless. So, many of the people who come here to eat Qingziliang are lining up to pack it up and take it home, so that their family members can also taste the coolness of the heart.　It's really amazing to see how well this little Qingmian Ryou can do. Good Qinglian stalls, usually ten, ten hundred, one by one. In Haikou, the location of the better word-of-mouth Qingxinliang stalls are: Haidian Island, three West Road, opposite the vegetable market; Wanlv Garden in the past a little past the four-dimensional cinema, with the old coconut, very special; Guoxing Avenue, a go to see a lot of; Hongchenghu Road (formerly Qiongshan City) 38 road public **** the starting point of the bus station, and so on.　Hainan Qingzuliang general practice: First of all, the red dates, green beans, barley, taro, watermelon, quail eggs, dumplings, etc. Separate cooked, do not cook too bad, fishing dry. Then prepare cool water, preferably in the freezer, otherwise you have to prepare the ice; and then prepare brown sugar, brown sugar syrup is the best, and then mix the above ingredients together, mixed with coconut juice or brown sugar water can be blended into a bowl of summer refreshing drink.
