Hello everyone:
You may know that leetcode has created a server in China and also new contest system although they have the same question as us server. They calculate the contest rating according to their rank in China's contest (where less people join the contest) so they could higher contest rating than if they joined the contest in us server. However, the global ranking also included them, so one has bad performance in contest could get higher global ranking if they joined the contest in China's server, which makes me feel bad because I am a Chinese who join the contest in us server and has a bad global ranking.
