On the historical changes of 3,000 words in China in the last hundred years from the changes since the Four Dynasties.

The taste and consumption of tea in China have generally undergone five changes:

First, in ancient China, tea was originally used as a drug to detoxify and treat diseases. Legend has it that Shennong tasted all kinds of herbs in the world, "seventy-two poisons are encountered every day, and all poisons are cured with tea", so he felt grateful for saving his life and broadcasted the method of planting in the world. Just like frying Chinese medicine today, fry its juice and take it. The Book of Tea also points out that symptoms such as "thirst, stagnation, brain pain, drowsiness, limb annoyance and joint discomfort" can be treated by drinking tea. Second, China's way of drinking tea entered the second stage after "boiling" in Han Dynasty. At this time, tea has developed from medicine to a popular drink. Guo Pu in Jin Dynasty called it "can be boiled into soup to drink" in Er Ya Zhu. The words "boiled" and "soup" here indicate the characteristics of drinking tea at that time. According to "Guangya" quoted in "Tea Classic", leaves were picked between Jing and Ba to make cakes, and old leaves were made into rice paste. If you want to cook and drink, fry until it is red, mash it, put it in porcelain, cover it with soup, and mix with onion, ginger and orange. Sober up and sleepless. What is cooked in this way is porridge-like soup, so it is also called "tea porridge" After the Tang Dynasty, salt was also widely used. Milk tea popular among Mongolian and other ethnic minorities, butter tea popular among Tibetans.

Third, "flooding" means smashing tea cakes into tea powder, adding seasonings and brewing with boiling water. This method was very popular in the Tang Dynasty. After the Song Dynasty, no seasoning was added, but it is still very different from drinking tea today, that is, tea must be made into powder, and the drinking method is quite similar to drinking brick tea today.

Fourth, it was not until the Ming Dynasty that drinking tea entered the present stage of tea making. According to Shen Defu's Wanli Wild Collection, from September of the 24th year of Hongwu (13 19), a dragon group was set up, but tea buds were picked to advance. ..... According to the seasoning of tea, it is mashed into pancakes, which has a twisted taste. ..... Today, people only take the essence of the first yin, buy a raft from the spring, sip it as soon as they soak, and then they will worship drinking forever. " It is clearly stated here that the method of making tea buds brewed with boiling water without adding auxiliary materials began in the early Ming Dynasty, but the wind of tea-making still coexisted with the method of tea-making for a long time.

The fifth is "cooking". At present, the main way of tea consumption in society is to make tea, still drink tea, but there is no shortage of boiled tea. Since 1990s, food science and technology workers in Taiwan Province Tea Improvement Farm have created a new kind of gourmet "tea feast" on the basis of scientific analysis and appraisal, which not only enriches the tea culture, but also is a revolution in the history of tea drinking. This "tea banquet" has 1 1 dishes, all of which are made of famous China teas. They are green tea salad, frozen tea tofu stuffing, black tea shrimp, qimen black tea diced chicken, steamed cod with fragrant slices, Tieguanyin stewed chicken, tea steamed stuffed bun, Bai Hao oolong stewed beef, smoked chicken with black tea, fragrant tea ribs and bamboo balls. Chinese food and "tea ceremony" are perfectly integrated and really complement each other. Fortunately, in recent years, a new edible tea product "natural ultra-micro green powder tea" has appeared in Jintan City, Jiangsu Province. It will bring great changes to the traditional way of drinking tea. Viewing foreign architecture from the changes of quadrangles

The traditional residential form in China is mostly quadrangle layout, and quadrangle is the most ideal residential form for China people. Siheyuan is symmetrical according to the housing on the east and west sides of the central axis, with the main room facing south, wing rooms, wing rooms and small courtyard on the east and west sides. The courtyard is paved with floor tiles, and flowers and trees can be planted on both sides to form a comfortable and quiet living environment. The quadrangles in Beijing are typical of this kind of houses.

After 1900, Britain, France, the United States, Russia, Japan and other countries successively built embassy districts in Beijing and residential buildings in Tianjin Concession, with European and Japanese architectural styles. In order to facilitate the residence of foreigners, Beijing has built the Six Kingdoms Hotel, which is 7 stories high, separated by red walls and pilasters, and decorated with European classics. This was the tallest residential building in China at that time.

At that time, the two deltas with the most local characteristics were the Yangtze River and the Pearl River. Most of the houses in Jiangnan water town are quadrangles. Bridges, flowing water, houses and docks constitute a unique landscape painting in southern China.

Since foreigners entered the Yangtze River valley, Shanghai's population has soared and land prices have soared. Since 1950s, a number of low-cost wooden houses have been built in the form of European townhouses, forming the original alley houses. In 1970s, brick-wood structure was adopted to design the unique Shikumen Lane residence in Shanghai, which is a group living style and the main form of residence in Shanghai. Shikumen is mostly built in rows in neat alleys. It is an adjacent house with brick and wood structure, which was born out of traditional quadrangles. The door is vertical and deep, and the adjacent Shikumen houses are on both sides of the aisle. At the beginning of the 20th century, many cities in the south of the Yangtze River also appeared in the form of group living in alleys, so the traditional living form of single-family houses in China began to be broken.

In the Pearl River Delta, including a part of Fujian, at the beginning of the 20th century, overseas Chinese who made a fortune or had savings began to invest in their hometown. Many local houses are western-style or a combination of Chinese and western styles, and the towers are very distinctive. For example, in Kaiping City, Guangdong Province, there are more than 2,600 watchtowers with different shapes, and quite a few of them were built in the early 20th century. Their styles include Roman, Turkish, French, British, Italian, German blockhouses and the combination of Chinese and Western styles. They are magnificent and colorful, showing all the European customs, making it hard for tourists to believe that this is the countryside of China. The reason why overseas Chinese families want to build their houses into watchtowers imitating European ancient buildings is mainly because they are relatively rich in the local area and are afraid of bandits' robbery. Therefore, the watchtower is generally 5-6 stories high. With the watchtower, the sense of security is enhanced.
