"sillimanite construction site" should be "sillimanite construction sites" (plural). 2. "the price of each manufacturer's equipment will not be too high" could be clearer as "the prices of each manufacturer’s equipment will not be too high". 3. "between manufacturers" is awkward and could be rephrased for clarity, perhaps "among manufacturers". 4. "the cost of transportation equipment is relatively low" could be enhanced to "the cost of transporting equipment is relatively low". 5. "Get Price More" should be "Get Price" or "Get More Prices". 6. "Jaw Crusher" and "Impact Crusher" should either maintain consistent casing (all capitalized) or follow a consistent format (capitalize only the first letter). 7. "Materials (brochures, catalogs）" should have a closing parenthesis that matches the opening one, it should be "Materials (brochures, catalogs)". 8. "To be Our Agent" should be rephrased for clarity, perhaps "Become Our Agent" or "To Become Our Agent". 9. "After-sales Services & Spare Parts" should follow consistent formatting with "and" instead of "&" if the previous bullet points use "and". There may be other areas for stylistic improvement, but these are the primary spelling, singular/plural, and punctuation issues. --- 【第 4 段建议】: 1. "WhatsApp:+86 13761974616" 应为 "WhatsApp: +86 13761974616"（在“WhatsApp:”和“+86”之间添加空格）。 2. "Sales Hotline: 0086-21-58386189" 应在 "0086-21-58386189" 和 "0086-21-58386176" 之间添加适当的符号，建议使用分号或换行（保持一致性）。 3. "Back" 后应有标点符号（建议使用句号或其他适当符号）。 4. "Top" 后应有标点符号（建议使用句号或其他适当符号）。 5. "Expand" 后应有标点符号（建议使用句号或其他适当符号）。 6. "for PPC参数传递" 中的 "参数" 和 "传递" 之间缺少空格，建议改为 "for PPC 参数传递"。 请根据需要进行修改。
