Why is Riven called Ray MengMeng?

Because in the animation, Wen Rui came to work in Izriel Hotel while escaping from the chase. When she was at work, Blade Ying came to the hotel and asked her name. She casually said my name was MengMeng, so everyone called me Wen Rui: Rui Mengmeng.

Raven, the blade of exile, is a hero in the competitive game League of Legends. In fact, Riven has very high requirements for operation. She can kill or lead your team to victory in Pusai, but you need to be more familiar with her skills if you want to take her to the ranking. In short, her playability is quite high, and she needs to be familiar with skills and be able to better connect skills.
