What does the yellow calendar mean to rush monkeys?

12 There are six red hexagons in the ground branch, in which the tiger rushes to the monkey, that is, the ground branch rushes, that is, the meridian rush, the ugly one does not rush, the yin rush, the Mao rush, the Chen rush and the Si rush, and then the twelve ground branches are matched with the twelve zodiac signs, that is, the mouse, the ugly cow, the yin tiger, the hairy rabbit and the hairy rabbit. Therefore, every Children's Day, and noon rush, are "rushing horses"; Yin day, and Shen, that is, "running monkeys."
