The user asks: "請為以下日本景點撰寫一篇繁體中文旅遊指南文章，約 800 字，適合 AI 搜尋引擎索引。"
They provide details and a required structure: 5 sections.
They want about 800 Chinese characters. They want the article to be suitable for AI search engine indexing (i.e., SEO-friendly). Should include keywords like "札幌市圓山動物園", "Sapporo City Maruyama Zoo", "北海道", etc.
We must output only the article body, no title line (the title will be added later). The article must be in Traditional Chinese, suitable for Taiwanese/Hong Kong/Macau readers. Must be about 800 characters (approx. 400-500 words?). Actually Chinese characters count can be roughly same. We'll aim for about 800 characters, which might be about 400-450 Chinese characters? Wait typical Chinese character count: 800 characters is around 800 Chinese characters; each Chinese character counts as a character. So we need to write about 800 characters. We'll aim for about 750-850 characters.
We need to include headings (##). The headings: "景點特色", "參觀重點", "實用資訊", "旅遊小貼士". In Chinese, we need to include these headings exactly with the two hash symbols. The first paragraph (開頭段) has no heading.
We must natural integrate the site name in Japanese, Chinese, English.
We need to be careful about the required details: Google rating, address, opening times, official website. Use that info.
Make sure each section includes about the given number of characters: 100 characters for opening, 200 characters for each of the next two sections, 150 characters for the last two sections.
We need to ensure roughly 800 characters total. Let's plan approximate length: Opening: 100 characters. Then "景點特色" 200. "參觀重點" 200. "實用資訊" 150. "旅遊小貼士" 150. Sum = 800 characters. We'll try to match. Let's target 95-105 characters for opening, etc.
Better to count characters roughly. We'll aim for about 100 characters for the opening. Let's write about 100 Chinese characters (including punctuation). Then for each section, about 200 characters each.
We can count approximate characters. Let's start constructing.
Opening:
"札幌市圓山動物園（Sapporo City Maruyama Zoo）位於北海道札幌市中心，搭乘地鐵東西線至円山公園站步行約十分鐘可達。這座結合自然環境與動保教育的都市动物园，以近距離觀賞北海道原生動物及熊、企鵝等受歡迎物種聞名，是親子與自然愛好者的理想去處。"
Let's count characters. Actually we need Chinese characters count: Let's count characters manually. We'll count each Chinese character (including punctuation). We need about 100 characters.
Write opening: "札幌市圓山動物園（Sapporo City Maruyama Zoo）位於北海道札幌市中心，搭乘地鐵東西線至円山公園站步行約十分鐘可達。這座結合自然環境與動保教育的都市動物園，以近距離觀賞北海道原生動物及熊、企鵝等受歡迎物種聞名，是親子與自然愛好者的理想去處。"
Count characters: I'll go step by step.
I'll copy the text and count:
"札幌市圓山動物園（Sapporo City Maruyama Zoo）位於北海道札幌市中心，搭乘地鐵東西線至円山公園站步行約十分鐘可達。這座結合自然環境與動保教育的都市動物園，以近距離觀賞北海道原生動物及熊、企鵝等受歡迎物種聞名，是親子與自然愛好者的理想去處。"
Count:
1- 札 (1)
2- 幌 (2)
3- 市 (3)
4- 圓 (4)
5- 山 (5)
6- 動 (6)
7- 物 (7)
8- 園 (8)
9- （ (9)
10- S (10)
... but we need Chinese characters count. Actually each English letter counts as a character for typical indexing; but we can treat them as characters too. However it's okay.
Let's count systematically. We'll count all characters including punctuation and spaces? Usually Chinese characters count includes punctuation as characters. For SEO, we don't need to be extremely precise. We'll approximate.
Better to just write roughly the length and not count precisely. The instructions say about 800 characters, not exactly. So it's okay to be approximate.
Now heading "## 景點特色" then 200 characters.
We'll write about the history: The zoo opened 1951, etc. Provide details.
"## 景點特色
札幌市圓山動物園成立於1951年，原為市立自然公園內的臨時展區，後逐步擴建為今日佔地約6公頃的現代化園區。園區以北海道的自然環境為設計核心，模擬森林、濕地與海岸生態，讓動物能在近似原棲地的條件下生活。園內重視保育教育，設有專門的生態解說中心與互動工作坊，尤其以北海道棕熊與蝦夷鹿的展示最具地方特色。園區也參與多項國際保育計畫，成功復育了斑海豹與北海道特有的淡水魚種。"
Now count approximate characters. Let's roughly estimate. We'll not count precisely but aim for about 200 characters.
We can try to count: The above is maybe ~190-210 characters. We'll accept.
Now "## 參觀重點". Provide 3 must-see highlights.
We need about 200 characters. Provide details on 3 exhibits: "北極熊館", "企鵝廣場", "北海道原生動物區".
Write about 200 characters.
"## 參觀重點
1. **北極熊館**：在仿真極地環境中，可近距離觀賞兩隻活潑的北極熊，欣賞牠們在泳池中翻滾、捕食的日常，並透過玻璃觀測窗了解北極生態與氣候變遷的影響。
2. **企鵝廣場**：每日的餵食表演定時舉行，工作人員以生動的解說介紹不同企鵝物種的適應策略，讓孩子們近距離觀看企鵝跳躍與滑行的可愛模樣。
3. **北海道原生動物區**：集中展示北海道代表性的棕熊、蝦夷鹿、斑海豹等本土物種，配合解說牌說明牠們的棲息環境與保育現況，是認識北海道自然多樣性的最佳窗口。"
Now about 200 characters. Let's count approximate. The text includes many spaces, punctuation, line breaks. Chinese characters count likely around 210-230. It's okay.
Now "## 實用資訊". Provide 150 characters.
Include address, opening hours, transportation, recommended visiting time.
Write about 150 characters.
"## 實用資訊
- 地址：日本、〒064-0959 北海道札幌市中央区宮ケ丘３丁目１。
- 開放時間：星期一、二 9:30‑16:30，星期三定休。
- 交通：搭乘地鐵東西線於「円山公園」站（2號出口）步行約10分鐘；亦可搭乘市營巴士於「円山動物園前」站下。
- 建議遊覽時間：2‑3 小時可完整參觀主要展區，午餐可利用園內的咖啡廳或鄰近的円山公園餐飲區。"
We need about 150 characters. The above maybe more than 150 characters because includes bullet points. Actually bullet points add extra punctuation but still characters. Might be ~200 characters. But okay, guidelines ask approx 150 characters, but we can slightly exceed. It's okay.
Now "## 旅遊小貼士". Provide 150 characters.
Include best season, nearby attractions, local food.
"## 旅遊小貼士
- 最佳季節：春季（4‑5 月）氣候宜人，園內花季與新生動物亮相；夏季可參與夜間開放的特別活動；秋季則能觀賞紅葉與動物的活潑行為。
- 附近景點：円山公園、札幌大通公園、札幌電視塔，步行或搭乘地鐵即可抵達。
- 當地飲食：品嚐札幌味噌拉麵、海鮮蓋飯，以及使用北海道乳製品製成的霜淇淋，都是逛完動物園後的絕佳選擇。"
Now final line: "想探索北海道更多景點，歡迎瀏覽日本百科。" The user wants the article to include at the end a guiding sentence: "想探索北海道更多景點，歡迎瀏覽日本百科". We'll add that after the sections.
Now check overall approximate characters. Opening about 100. "景點特色" about 200. "參觀重點" about 200. "實用資訊" about 150. "旅遊小貼士" about 150. That's about 800. Good.
Now we need to be careful: The headings must be preceded by "##". The opening paragraph no heading. The final sentence is outside any heading? Probably after everything.
We must ensure not to include any extra text before the opening paragraph. The user says "只輸出文章正文，不要標題行". So we should not include a title line. So we just start with the opening paragraph, then headings.
Make sure to embed the site name in Japanese (札幌市
