We need to produce a 6-8 paragraph article, each 150-250 words, total >=1500 words, with title fixed but not output title? The user says "直接输出正文，不要标题". So we output only the body, but must be 6-8 paragraphs each 150-250 words. So total about 1500 words. 6 paragraphs 150 = 900, 8 paragraphs 250 = 2000, so we need within 1500-2500? Must be at least 1500 words, can't be less than 1050. So must be >=1500 words. Let's aim for 7 paragraphs of ~220 words each = 1540 words. Provide natural, conversational style, no AI jargon, no listed keywords, avoid AI detection patterns. Use specific details, avoid formulaic phrasing.

We must avoid the banned keywords list. Don't use "、". Also avoid opening with "" etc. Must start directly. Use short sentences, active voice.

We need to ensure each paragraph is 150-250 words. Let's craft 7 paragraphs of ~220 words each.

We need to be careful with word count. Let's approximate.

Paragraph 1: ~220 words. Introduce title concept, excitement, why 318 route matters, mention electronic map.

Paragraph 2: Talk about planning, features of the electronic map, offline capability, points of interest, etc.

Paragraph 3: Talk about key stops: Chengdu, Dujiangyan, Qingcheng, etc. Specific anecdotes.

Paragraph 4: Talk about scenery: mountains, rivers, sunrise at Balang Mountain, etc.

Paragraph 5: Talk about practical tips: fuel, weather, parking, accommodation, apps.

Paragraph 6: Talk about unexpected moments, local food, tea houses, interactions.

Paragraph 7: Concluding reflection, tying back to title, urging readers.

Need to ensure each paragraph length 150-250 words. Let's craft paragraphs with about 220 words each. Count words roughly.

I'll write paragraphs, then count approximate words.

Paragraph 1: Let's draft ~220 words.

"早晨的成都还带着霧氣，我把手裡的手機打開，裡面已經排好好像在等我發起引擎的路線圖。這張318自駕路線圖不只是條線條，而是把整條山海相連的旅程壓縮成一個指尖的指南。你可以直接下載它，無論是高清的矢量圖還是分段式的提示，都不需要再跑去租車公司問路。我第一步就是把這張圖放在車載顯示器上，然後把所有的里程標記、加油站和急修站一目了然。這樣的設計讓我免除了一路上不斷查地圖的麻煩，也避免了因為信號不好的時候突然找不到停車點。整個過程從打開App的那一刻起，就彷彿和一位老友一起踏上了路，而這條路線正是我心中不可錯過的自駕聖地。"

Count words? Let's count roughly. In Chinese, word counting is ambiguous, but they likely count words as characters separated by spaces? Usually they count characters? But we can approximate length. However they want 1500 Chinese characters? Actually they said "字数要求：必须写满1500字，不能少于1050字！" That likely means Chinese characters count. So we need at least 1500 Chinese characters. Each paragraph 150-250 Chinese characters. So we need to ensure each paragraph length in characters between 150 and 250 Chinese characters. Not words. So we must produce paragraphs of about 150-250 Chinese characters each. That's easier: each paragraph ~200 Chinese characters. So we need 6-8 paragraphs each 150-250 characters. Total >=1500 characters. So we need to produce about 7 paragraphs 200 = 1400, need >=1500, so 7220=1540 characters. So we need to count characters.

Thus we need to produce Chinese characters, not English words. So we need to count characters. Let's aim for roughly 220 characters per paragraph, 7 paragraphs = 1540 characters. Provide them without title.

We must avoid banned keywords and AI detection patterns.

We must ensure each paragraph 150-250 Chinese characters. Let's craft paragraphs of about 200-230 characters each.

Let's draft paragraph 1 ~210 characters.

Paragraph 1: "早晨的成都還帶著霧氣，我把手裡的手機打開，裡面已經排好好像在等我發起引擎的路線圖。這張318自駕路線圖不只是條線條，而是把整條山海相連的旅程壓縮成一個指尖的指南。你可以直接下載它，無論是高清的矢量圖還是分段式的提示，都不需要再跑去租車公司問路。這樣的設計讓我免除了一路上不斷查地圖的麻煩，也避免了因為信號不好的時候突然找不到停車點。整個過程從打開App的那一刻起，就彷彿和一位老友一起踏上了路，而這條路線正是我心中不可錯過的自駕聖地。"

Now count characters. Let's count manually (including punctuation?). Usually Chinese characters count includes punctuation? Probably just characters, but punctuation may be counted too. Let's approximate characters count.

I'll count characters (including punctuation and spaces? There are no spaces). Let's write the paragraph as a single string:

"早晨的成都還帶著霧氣，我把手裡的手機打開，裡面已經排好好像在等我發起引擎的路線圖。這張318自駕路線圖不只是條線條，而是把整條山海相連的旅程壓縮成一個指尖的指南。你可以直接下載它，無論是高清的矢量圖還是分段式的提示，都不需要再跑去租車公司問路。這樣的設計讓我免除了一路上不斷查地圖的麻煩，也避免了因為信號不好的時候突然找不到停車點。整個過程從打開App的那一刻起，就彷彿和一位老友一起踏上了路，而這條路線正是我心中不可錯過的自駕聖地。"

Now count characters. Let's count manually:

I'll number characters:

Wait I'm mixing. Let's do systematic count using groups.

Better approach: approximate length. It's likely around 200 characters. Let's trust it's okay.

But we need to ensure each paragraph is 150-250 characters. Hard to guarantee manually. But we can approximate. Provide paragraphs of roughly 200 characters each.

We'll produce 7 paragraphs each around 200-230 characters.

Let's craft each paragraph with careful length.

Paragraph 1: about 210 characters.

Paragraph 2: about 200 characters.

Paragraph 3: about 210 characters.

Paragraph 4: about 210 characters.

Paragraph 5: about 200 characters.

Paragraph 6: about 210 characters.

Paragraph 7: about 200 characters.

Total ~1500 characters.

We must avoid banned keywords. We must not use "、". Also avoid "" etc. Also avoid AI pattern like "". Also avoid "非常重要" etc.

We must not use "标题已确定" etc. Just plain text.

Let's write paragraphs.

Paragraph 1: start directly, talk about excitement, downloading map, etc.

Paragraph 2: details of map features.

Paragraph 3: key scenic spots.

Paragraph 4: scenery description.

Paragraph 5: practical tips.

Paragraph 6: unexpected moments.

Paragraph 7: concluding reflection.

Now write each paragraph with about 200 characters.

I'll write them and then count approximate characters.

"早晨的成都還帶著薄霧，我打開手機裡的下載頁面，看到一張標著318自駕路線圖的圖示。這張圖不只標出高速與山路，還把每個加油站、餐廳和休息區標得很清楚。只要點一下下載，就能把整條路線保存到車上，不管信號好壞都能隨時查看。這樣的便利讓我免去了紙張地圖的麻煩，也把行程的每一段都安排得井井有條。"

Now count characters (including punctuation). Let's count:
