Summary: the blessing bag is about 4 cm long, which is half the size of a credit card. It has been opened by a monk. There are scriptures, precious stones, sandalwood particles, ancient money, coarse salt and so on in the blessing bag.
The source of the blessing bag:
It is said that it originated from Japanese department stores in the late Meiji period. Shops and department stores in Japan often sell blessing bags after the Spring Festival or on auspicious days when shops are open. The price in Fu Bao is generally 1-200 yen. Although the price is reasonable, it is not reliable. Some stores often put unsold overstocked goods into Fubao to cheat customers.
So people often complain to newspapers, although occasionally lucky people can buy higher value ones. Because you have to pay before you can open the bag, consumers have no idea what's inside before they buy it.
Driven by curiosity, many people donated money for many times, so the business of "Fu Bao" is always good. Some department stores even launched hundreds of thousands of "Fu Bao" in one breath, making enough money.
