Before things start, there must be a start-up process. We can take neutral gas and residual gas as the starting steps before starting gas every month. That is to say, any monthly order must be commanded by Zhong You and Yu Qi for several days before it can be formally commanded by Benqi.
Based on this, in four months, command residual gas first, then command middle gas, and finally command local gas; In April, command residual gas first, then command gas storage, and finally command local gas. In the first month of April, I was also the first commander of Yu Qi, and then I was the commander of Benqi.
The above rule is called the division of labor between the people and Yuan commanders. I hope my answer can help you.
