I'm not sure how many people in the country have the name Wang Jie because the name is just a personal identification symbol and there is no fixed number. China's population was huge, and there were many people with the same name, so it was impossible to determine the number of people named Wang Jie in the country.
There were quite a few players in Perfect World. Although the number of players in the domestic version was relatively small, there were still some regular old players who continued to play the game. The number of players in the international version was 10 times more than the domestic version. This was probably because the international version's advertising was more popular. However, it was important to note that Perfect World did not promote the domestic version, so the number of new players was relatively small. Most of them were transferred from the international version to the domestic version. Therefore, in general, the number of players in the perfect world was relatively high.
The Legend of Wuxia was a Chinese martial arts novel. It did not explicitly mention the existence of the world's number one swordsman. There were many famous swordsmen in the novel, such as Yan Qi, Ye Kai, the Four Friends of Mei Zhuang, etc., but there was no mention of who was the best swordsman in the world.
