What is the heavenly stem?

Heavenly stems refer to the ten heavenly stems in heavenly stems and earthly branches.

Tiangan, an ancient Chinese character sequence symbol in China, contains 10 characters:? A, B, C, D, E, Kyrgyzstan, G, Xin, Ren and Gui are used circularly. In ancient times, China and other countries with cultural circles of Chinese characters often used them to name, sort and date.

Heavenly dryness began in Shang Dynasty at the latest. The most obvious evidence is that the titles of business leaders are merchants, B, B, C, Yi Ding, Zhu Ren and Zhu Gui. Officially naming these ten symbols as heavenly stems should be related to earthly branches: the stem is the main stem and the branch is the branch, and the two relative names should appear together.
