鱼的记忆驴的脾气
[yú de jì yì lǘ de pí qì]
This nickname reflects the user's self-mockery or humor, implying they might have a good memory (like a donkey, which is known for having a great sense of direction and memory) while forgetting things fast (as people often say fish only remember things for seconds). It shows a mix of stubbornness and easy forgetfulness.
