What do you mean by forty-nine fifty days on the avenue? What does forty-nine mean?

Forty-nine days on 50th Avenue means that everything can't be perfect, there are always shortcomings, everything can't be absolute, but there are always opportunities. In ancient times, there were two methods of divination: divination and divination. The divination is mainly tortoise shell, and the divination is mainly yarrow. The method of divination is explained in detail in the Book of Changes. The method is to take 50 yarrows, leave one unused, and only use 49 divinations. Fifty yarrow trees represent everything in the world. Unused refers to the number of Tai Chi and Great Yan before the death of heaven and earth. If one of them is omitted, it can be understood that everything comes from Tai Chi. The avenue is fifty, and Tian Yan is forty-nine. It's always imperfect, but there's always a chance.
