What does lpl50 mean?

Lpl50 is a stalwart, and lol's list of 50 people refers to professional player A Le, because rng originally reached an oral agreement with the cursed player during the transfer period. But I didn't expect the curse to come. Later, I went to A Le to have a try. Therefore, instead of telling A Le to cancel the test, they decided to let Xiaohu place an order. So later, after A Le, rng staff told him not to try. And transferred 50 yuan to A Le, saying that it was used to reimburse the fare and buy milk tea. A Le vomited wildly and told his fans that he had been stood up by rng, so he named his id "Fifty dollars on the order".
