2. The great economic development in the Song Dynasty (ten times in the Ming Dynasty, five times in the Qing Dynasty and two or three times in the Tang Dynasty) made the most money, far exceeding that in the Han and Tang Dynasties, and it was still far from enough, so it was changed to paper money. Later, Jinyuan also used paper money.
Gold was used in ancient times. Later, Buddhism rose and the Buddha statue was gilded. There is less and less gold.
4, the use of silver is relatively late, mainly using silver until the Ming Dynasty. Generally speaking, one or two pieces of silver is equivalent to one thousand pence, sometimes it goes up and down. For example, after the geographical discovery, silver from the United States flowed into China, and the price of silver came down. At the end of the Qing Dynasty, opium was imported, and silver flowed out, and the price of silver was expensive again. During the Taiping Heavenly Kingdom, a silver coin was equivalent to 15600 words. But most of them still take one or two pieces of silver as 1000.
5. A thousand words are also called consistency, or a word.
6. One kilo equals sixteen taels, and one tael equals twenty-four baht, which is ten dollars. Ancient gold is different from present gold. Generally speaking, the Ming and Qing dynasties were equivalent to 1. 1- 1.2 Jin. One or two ounces of silver is equivalent to 400 grams, and one or two ounces of silver is equivalent to 40 grams of silver and 4 grams of gold.
7. Before the Song Dynasty (because silver was rarely used at that time), "one yuan" was the meaning of the article. After the Ming dynasty, it means more than one dollar, which is equivalent to one hundred articles.
