大概他想赢而我姓苏
[dà gài tā xiăng yíng ér wŏ xìng sū]
Translated as 'Perhaps he wants to win and I happen to have Su as my surname'. A mix between a pun and a personal reflection on the competitiveness between oneself and 'he/another party', possibly adding humor about having the surname 'Su'. This username may indicate a casual attitude towards competitions, suggesting that although one's surname may not affect the outcome, there is a mutual desire to excel. The 'Su' here doesn't convey any additional meaning but serves humorously or idiomatically, similar to how names are used humorously or idiomatically in various languages
