If Andy Lau and Jacky Cheung hold concerts at the same time, who will have more concerts?

There is no doubt that there are more people in Jacky Cheung than in Andy Lau. I forget when they sang at the same time in the stadium of 80 thousand people in Shanghai. Xueyou's attendance rate is much higher than that of Ge Hua, and the tickets outside Xueyou's concert will not be reduced no matter how long, while Ge Hua's attendance rate is obviously less than that of Xueyou, and the tickets outside have been reduced since he started singing. Because I went to all their concerts and bought tickets from outside.
