We need to produce a 1500+ word article, 6-8 paragraphs each 150-250 words. Must start directly with content, no title. Title already given, but output should be just the article body (no title). Must be natural, conversational, senior media person style. Must avoid AI clichés. Must be at least 1500 words, cannot be less than 1050. Need 6-8 paragraphs, each 150-250 words. So total word count must be >=1500. Let's aim for 7 paragraphs of ~215 words each = 1505 words. Need to ensure each paragraph length between 150-250 words. Let's craft 7 paragraphs of about 215 words each.

We need to avoid AI banned words. Use natural style, no "". No "让我们". Use short sentences, active voice. Provide concrete examples.

Paragraph 1: open with title theme, talk about maps and silent boundaries. 215 words.

Paragraph 2: historical examples of unmarked borders, like tribal lands, secret zones.<
