Everyone has a birthday. What is the solution to the cross?

Looked at it and smiled. A group of young people, don't pretend to understand if you don't understand.

It is indeed a birthday cross. For example, the twelfth lunar month in the Year of the Monkey, August in a leap year, and beginning of spring at that time. This is the beginning of the spring of the Year of the Rooster. Then the twelfth lunar month of that year is January of the following year. There is a cross. Friends, if you don't know how to read more books and ask more questions, respect the China tradition.
