Interpreting football geography

I need to respond to the user’s Chinese statement about football geography. They're mentioning that the U-15 national team’s final opponent, Bangladesh, doesn’t encompass all of Bengal. This suggests they might want an explanation about the difference between the historical region of Bengal and the modern state of Bangladesh. I'll mention how historically, Bengal included parts that are now in Bangladesh and Indian states like West Bengal and even parts of Assam, Bihar, and Jharkhand.Clarifying Bengal's geography

I realize that Purulia is actually in West Bengal, not Jharkhand. The Rarh region extends into Jharkhand, but the Chota Nagpur area was historically separate from Bengal. The cultural-linguistic region primarily includes Bangladesh, West Bengal, and parts of Tripura. While Tripura has a Bengali majority, it’s not historically part of Bengal. Some also consider Bengali-speaking areas like the Barak Valley in Assam and parts of Jharkhand as part of Bengal. The historical context of the British partition of Bengal is crucial to understanding these distinctions.Summarizing Bangladesh vs. Bengal

It seems the user is looking for a concise explanation following the CLI guidelines. They haven't requested any shell commands or file edits. I’ll differentiate between "孟加拉国" (Bangladesh) and "孟加拉" (Bengal region). I can explain that "Bangladesh" refers to the country, while "Bengal" can denote the larger region. I might mention the Ganges-Brahmaputra delta, capitals Dhaka and Kolkata, and the shared Bengali language. I'll also note the "国少末战" refers to China's U-15 national team, playing their last match against Bangladesh. I’ll present this in a neat bullet point format!Differentiating Bangladesh and Bengal
I don't need to use any planning tools since this is straightforward. I’ll follow the final answer structure and provide a title and a concise bullet list with 4–6 items.
