Thank you, that's exactly the explanation I was after!kinda close to what they hear from stream, average chinese just don't bother to learn the full spelling of those IDs, usually the first letters.
Hera is known as hera, easy, viper is known as vip for many years, liereyy is too hard to spell but lili just sounds similar.
I wonder if us "westerners" are doing something similar with the names of Asian players
