What do you mean by "double officials"

Go to the clause. In the official sub-stage of Go, officials with a numerical value of two orders are called double officials.

Pay attention to the problem of dual officials:

(1) The "immortal second order" mentioned here refers to the double-back second order, so special attention should be paid.

(2) A word opposite to "double officials" is "single official". A single official is an official with an index value of 0, and it is the official with the smallest disk. (A single official is not an official with a value of 1. Don't make a mistake! )
