Later, in New Yuefu, Madame Li and Gujia Fox, the themes of "eunuchs confuse people" and "foxes seduce and harm people" were repeatedly emphasized, Clearly publicize the harm, but admit that "people, non wood and stone have feelings", can not be eliminated, so the way to solve the problem is "better not to encounter the city". But in the actual writing of Song of Everlasting Regret, he obeyed the human instinct and emotion towards beauty expressed in folk love stories. In this way, the whole story has a more profound and complex meaning: it not only describes the true beauty, but also the true and evil, and directly links the two; There is a passage in the book of "The Collection of Beautiful Feelings" and "The Legend of Everlasting Regret": Uncle Xiang's mother said, "If it is beautiful, it will be very evil." Li Yannian's song said, "It is also called" to overthrow the country and restore the city. ". This passage probably represents the thinking of the middle Tang scholars on this issue. One of the basic principles Bai Juyi followed when writing the Song of Everlasting Regret is not to erase the "beauty" because of the "evil". Although its main theme seems to deviate from the condemnation of "very evil", the content of "very evil" itself has not been obliterated after all, which in turn enriches the meaning of "very beautiful".

Used by some manufacturers Inlet valve In addition to accessories, other supporting raw materials have been localized.
Notes:
(1) The so-called pre foaming means that 80% of the polyurethane foaming agent has already foamed, and the range of the post foaming is very small, so that workers can use the foaming gun with good hand strength, simple and convenient, and no waste of glue. The post foaming means that the glue is gradually thicker several times than when it is punched out, so that it is difficult for workers to buckle up their hands, easy to waste glue, and 1/3 less waste, In addition, the cured adhesive is easy to damage the doors and windows, such as the common adhesive from the market factory.
