Now describe a person who is thrifty, extravagant and irritable, and we will say that this person is "not a fuel-efficient lamp." On the contrary, that is to say, "saving oil lamps" is a metaphor for people who are easy to get along with or timid. Chen Defu now said in the article Qiong Kiln Culture Goes to the Country: "As we all know, the proverb' not a fuel-efficient lamp' has been widely popular in China's literary works, spoken language, film and television works and audio-visual works for many years, and it is very popular in all parts of China, with high frequency and wide application. Its meaning is also clear and well known, and the general idea is extraordinary but not simple. If someone is "not a fuel-efficient lamp", compliment means being smart, capable, well-founded, well-informed, full of ideas and high wisdom; This language is derogatory in most cases, implying that someone is scheming, cunning, wily, difficult to deal with, unwilling to be lonely, never suffering, always harming others and benefiting themselves. " We don't know when the word "fuel-efficient lamp" originated, but it originated from the fuel-efficient lamp invented by Qiong Yao in the Tang Dynasty, which is very obvious and beyond doubt. The theory of "saving oil lamp" originated from Lu You's poems, and this kind of "saving oil lamp" did exist in ancient times. "Song Wengong concentrated, there is a poem" Fuel-efficient Lamp ",which is now hidden in Han Jia, and the lamp is also covered. It's easy to open a small mouth at one end and pour cold water into it every night. Ordinary lamps are dried by fire, so they dry quickly. Otherwise, they will save several and a half times the fuel. " (Notes on Lu You's Old Learning Temple in Song Dynasty, Volume 10). In ancient times, there were no electric lights like today. In ancient times, lamps were usually used for lighting. Lights in the Six Dynasties usually consist of oil lamps, supporting columns and bearing plates. Most of its works are novel and diverse, and it still seems to be a work of art now. Oil-saving lamp is one of these lamps, which is made of ceramics. At first glance, the fuel-saving lamp is not much different from the ordinary lamp, except that its disk wall is a hollow interlayer, and there is a small round mouth on the side of the disk wall for injecting water into the interlayer. After cooling by injecting cold water into the interlayer, half of the oil can be saved. For example, the Chronicle of the Complete Works of Lu Fangweng records: "According to the book candle, it must be thick and short, no more than one foot. Thick is tolerant, short is close. Don't use copper lamps for book lamps, porcelain lamps are the most fuel-efficient. There are porcelain lamps in Shu, which can save half the fuel by injecting water into the lip orifice. The lamp method is seven inches high, six inches wide and the diameter of the lamp ring is two and a half inches. Choose the symmetrical one. " Provincial oil lamps were very popular in Tang and Song Dynasties. Shao Mu also gave provincial oil lamps as gifts to scholars and senior officials in the imperial court during the Han and Jia Dynasties. The history book says: "When Shao announced Shi Hanjia, he sent Chinese and Korean scholars according to the number of people. According to Wen 'an, it is also tasted as a famous dish in Yujin, so Han Jia has been producing this kind of thing for hundreds of years. " "Han Jia" refers to Qingjian County in the Han Dynasty, which was changed to "Han Jia" in the later Han Dynasty, north of Ya 'an City today. There is also a story about ancient provincial oil lamps. It is said that Yang Di is extravagant and dissolute, and fish begins to stink at the head and local officials also try their best to exploit people to please Yang Di, which makes people very angry. The autumn drought in the Central Plains coincided with Yang Di's expedition to Korea. On the way to March, the oil was urgent, and there was no oil when lighting at night. There was a man named Liu Fang in the army who suggested collecting oil from all over the country, and the people used special provincial oil lamps to light the lamps. At the latest, offenders pay heavy taxes, and the people can't even afford to save oil lamps. Meng, a celebrity in Jizhou, was very dissatisfied and led 700 people to launch an uprising. The slogan is "Leave the oil lamp to the emperor" and mix it with Yang Guangjun and Yang Di. "700 strong men killed countless enemies. It's a pity to be strong and die well. " Later, it was popular among the people that "Yang Guang is small and sweet, and does not save the oil lamp". Tianya blog this article address /blogger/post_show.asp?
