英语不好却认得wif
[yīng yŭ bù hăo què rèn dé wif]
Translating into 'Poor in English, But Know WiFi Password', the nickname might belong to someone who admits they aren't good at something (learning English in this case) but can manage well when it comes to practical needs (like finding a WiFi password), reflecting the humor and pragmatism of people in modern society
