What does Japanese yen mean?

This is a term used for birthdays. The so-called birth is the year, month, day and hour of birth, which are expressed in heavenly stems and earthly branches and one in heavenly stems and earthly branches respectively. Then combine the four time units of year, month and day with the four heavenly stems and earthly branches to record the time, which is eight words, so it is called a birthday. For example, at this time today (the fourth time is 9: 00-65438). The Japanese yen refers to the date of birth, which is the day in the above example, and the earthly branch of the Japanese yen is the earthly branch of the day, which is the child. By the way, the concept of earthly branch is actually what we call 12 Zodiac, that is, Ugly Son, Yin Mao and Tatsumi defend the sea in the afternoon. Correspond 12 earthly branch to year, that is, annual branch, monthly branch and month, daily branch and day (today's earthly branch is a child), and time branch is a time branch.
