南非世界杯揭幕战再现，美加墨世界杯首战：墨西哥vs南非（再续揭幕战情缘：美加墨世界杯首战，墨西哥对阵南非）

Clarifying World Cup details

The 2026 World Cup format expands to 48 teams, with the draw scheduled for late 2025, meaning the opponent isn't known yet. The user's mention of "Mexico vs South Africa" reflects the 2010 opener, which ended in a draw. I should correct any misinformation—since the draw hasn't occurred, I can't confirm that matchup. I need to clarify whether they're looking for news verification or to write something nostalgic about the teams. I can offer options like fact-checking or providing hypothetical analysis.Proposing options for World Cup info

I need to propose two options: First, if they’re looking for a news verification, I should clarify that FIFA hasn't confirmed the opponent yet. The opening match is set for June 11, 2026, in Mexico City at Azteca Stadium. The US will host its first match at SoFi Stadium in LA. There’s also a dispute about the field's width. The final is scheduled for MetLife Stadium in New Jersey. I need to present this information accurately!Summarizing World Cup schedule

In February 2024, FIFA announced that the opening match of the World Cup will take place at Estadio Azteca on June 11. On the same day, the USA will play at SoFi Stadium in Los Angeles, and Canada will host at BMO Field in Toronto. There were some controversies regarding SoFi's pitch size, but modifications were approved. It's important to mention that South Africa has not guaranteed qualification yet, so "Mexico vs South Africa" is speculative. If they want nostalgia, I can recap the 2010 opening match!Crafting a concise response

I need to check facts quickly: right now, the matchup isn't set since the draw hasn't happened yet, and South Africa hasn't secured qualification. I should also ask the user what they need: do they want me to verify information, write a preview, or create a comparison recap? Keeping this response concise is key. I’ll produce a neat answer in Chinese that includes these essential points.
