Guess first, go to the terms. The order of guessing first is: First of all, high-ranking people hold a number of Bai Zi, which will not be shown to others for the time being. The next paragraph shows a black dot, which means "odd number means black, and vice versa", and two black dots show "even number means black, and vice versa".
When the top management announced the number of albinos in their hands, the hands were naturally determined. When the two sides are in the same position, the elders will hold the children.

Detailed answer
By both sides of the game, the high-ranking (or elderly) person grabs a piece at will, and no one knows whether the piece he/she takes is odd or even. Then, guess in the next paragraph, if the next paragraph thinks it is odd, take a chess piece; If the lower player thinks it is flat, take two pieces. Then the high-level players will announce the number of pieces in their hands. If the low-level player guesses correctly, then he will start with the sunspot. If you guess wrong, take Bai Zi as an example, then people at the top will take the sunspot first.
On the whole, this is a fairly fair decision. Through random selection, both of them have a 50% chance of winning the first prize, and neither of them will suffer. Of course, this is also a way to decide who will go first in the Go game, while other methods, such as drawing lots, are also based on random methods and the principle of fairness and justice, so that both sides have the possibility of going first with the same probability.
