Who won the national football championship or Japan?

If China beat Hongkong with a slight advantage and Japanese beat South Korea with the same advantage one day later, the goal difference and points of the two teams will be exactly the same. According to official website's integral rule, there may be more than one champion. In other words, it is theoretically possible for China and Japan to be tied for the championship. However, according to the news that the reporter in front of Sina got from the inside of the national team, the national football team got another explanation from the organizing Committee-in the case of the same goal difference, the champion will be drawn by lot. Of course, whether it is a draw or a draw, as long as the national football team can give a satisfactory performance in the third game, then the third place in the championship is not important.
