我姓万也玩不起你
[wŏ xìng wàn yĕ wán bù qĭ nĭ]
'My last name is Wan (万), but I can't keep up with you.' This might reflect someone humbly admitting inferiority to another in a humorous or self-mocking way, especially considering their last name (Wan 万) sounds like “ten thousand,” traditionally denoting great magnitude or quantity.
