这条更像一则赛后快讯标题：国安3-0河南，分差达3球，追平足协杯决赛最大分差的纪录。你需要我把它扩成哪种内容？

Confirming FA Cup margin

The user stated that a 3-0 win ties the biggest winning margin in FA Cup finals, which means previous four finals had a 3-goal difference too. It sounds like they might be referencing a social post. I want to keep things straightforward, so I should confirm this, and ask if they’d like a recap, some stats, or match details. It’s important to note that the largest margin is indeed a 3-goal difference since the tournament moved to single-match finals.Clarifying FA Cup margins

I reviewed some recent FA Cup finals, and it seems that 3-goal margins aren’t very common. For example, there were finals like Shandong 1-0 Shanghai Port in 2021 and Shandong 2-1 Zhejiang in 2022. I’ll avoid specific details unless necessary, so I'll ask the user if they’d like a news brief, match stats, or key moments. I could also offer historical context about FA Cup final margins in Chinese, like a quick summary of notable games.
