It is the same as what I know. It also confirms that the referee only listens to the sound and not talks with VAR during the whole video, indicating that VAR is as difficult as the audience to confirm whether it is handball through video, therefore, the main responsibility lies in the border cut of redundant flags, and the flag language of the border cut is consistent with the later penalty (many people mistakenly believe that the edge referee is offside, but in fact, the offside flag needs to be pointed to the field in the end), it shows that the referee adopted the frontier ruling opinion under the condition of unknown truth.
