The "tianjing" you mentioned has been said in Shandong, Hebei, Henan and other Central Plains areas. This is the language of Jurchen, and the northeast Jurchen entered the Central Plains in the golden age. Tianjing also came in, which is "telere jiha" in Jurchen language, and literally translated into "Unfolded Money" in modern Chinese. telere means to unfold, open and bloom, and jiha has money and crops bloom. Because it is similar to the Chinese homonym "Tian Jing" (adding prosperity), "Tian Jin", "Tian Jin" and "Tie Jin", it was sinicized and entered the Chinese dialect. Later generations of Jin Jurchen were classified as Han nationality in the Yuan Dynasty.
tianjing has a lot of workmanship today, not only paper-cutting, but also painting, tie-dyeing, printing and so on.
In fact, the real linked money was only formed in the Qing Dynasty. As a Chinese culture, it may have evolved from Kunsheng, which is just a guess of scholars. However, in the northeast, it did evolve from the auspicious symbols of Shamanism, which was formed in the Jin Dynasty (Song Dynasty). Today, there is also a kind of white hanging money in Beijing and other places, in which the word "ling" is carved in Chinese and the money is wheeled around, which is very delicate and used on the board of ancestors. This is a witness to the evolution of shamanism believed by Nuzhen and later Manchu. Perhaps there is no such thing as hanging money in the Central Plains, which is the evolution of Shaman Jifu in the Central Plains. tianjing you mentioned is also one of the evidences.
