Wei Zi has been drinking cold drinks for several years.

Many friends like history, but I have to say that there are some things in history that you may not know. There are five cold knowledge in the history of China: cold drinks appeared in the Song Dynasty, and Cixi declared war on the world? The first one: cold drinks appeared in the Song Dynasty.

The practice of storing ice in winter and using ice in summer has existed since ancient times. 1600 years ago, during the Eastern Jin Dynasty, Nanjing began to make cold drinks to cool off the heat, but this was a privilege only enjoyed by the royal family. In the Southern Song Dynasty, because the scale of ice storage was greatly improved, civilians could also enjoy cold drinks made of ice.

At that time, a cold drink called "ice cream" appeared in Nanjing, which was the most popular. The great poet Yang Wanli left it after tasting it. "It seems greasy and cool, but it is actually condensed. The poem "the bottom of the valley is broken, the snow mouth is parted" shows that the cold drink that Yang Wanli ate is very similar to the current cold drink.

The second one: the source of spinach

The hometown of spinach is in Persia. More than 2000 years ago, Persians planted it as a vegetable, so until now, spinach has another name of "Persian grass". 2 1 year, the king of Nepal sent envoys to Chang 'an with spinach as a gift. Since then, spinach has settled in China.

Spinach was a rare food in the Tang Dynasty, and only dignitaries could eat it. According to the Six Classics of Tang Dynasty, there is a kind of cake in the palace. Spinach is cooked and mashed into noodles, and then processed into noodles, which are given to officials with more than nine products at banquets.

Third: the Japanese name was given by Wu Zetian.

Japan was also called Japan in history, but why did it change its name later? After Koguryo was destroyed by the Tang Dynasty in 668, Japan sent envoys to the Tang Dynasty in 669. This time, when the envoys to the Tang Dynasty appeared in front of the officials of the Tang Dynasty, they probably had already proposed to the Tang Dynasty that Japan should be renamed "Japan". This incident is recorded in the Collection of Ancient and Modern Books: "In the first year of Xianheng, the Japanese began to change to Japan and sent envoys to Heping Korea."

However, the Japanese envoy's proposal may not have been recognized by the Tang Dynasty at first. Guo Moruo's credentials to Japan in The Collection of Good Neighbours are "Asked by Emperor Taizong", which is an example. It was not until the first year of Emperor Dabao of the Ministry of Education that China officially recognized the Japanese title. At that time, Wu Zetian was in power, so the name was also given by Wu Zetian.

Fourth: Cixi declared war on the world.

On June 2 1900, Empress Dowager Cixi, who held the actual military and political power in the Qing Dynasty, made an unprecedented event, that is, declared war on the world. Cixi said in the "imperial decree" that she vowed: "Without it, it would be a pity to live; If it is a big slap in the face, it will be a showdown. " It is not the style of Lafayette who has lost his power and humiliated his country.

Fifth: the imperial edict is not necessarily golden.

In movies and TV series, golden yellow is almost the standard of imperial edict. The imperial edict in Ming and Qing dynasties has been extremely perfect, and the materials used in the imperial edict are also very particular. They are all brocade fabrics made of fine silk, and the patterns are mostly auspicious clouds and cranes, which are magnificent.

In the Qing dynasty, the bigger the official position, the more colors there were when the imperial edicts were issued, including seven-color imperial edicts, five-color imperial edicts and three-color imperial edicts. Imperial edicts issued to officials under five grades are pure white silk in a single color.
