The user wants a 1500+字 article, with title already set, but they say "直接输出正文，不要标题". So we output the article body only, no title. Must be 6-8 paragraphs, each 150-250 words. So roughly each paragraph ~180 words. 6-8 paragraphs *180 ~ 1080-1440 words. They require at least 1500 words. So we need more than 1500. If we produce 7 paragraphs of ~220 words each, that gives about 1540 words. Each paragraph 150-250 words, so okay. Must meet 1500字 requirement (Chinese characters count). Must not be less than 1050. So we need at least 1500 Chinese characters. Let's aim for 7 paragraphs of ~220-230 characters each, total ~1610 characters. Need to ensure each paragraph is 150-250 Chinese characters. Provide natural flow, avoid AI patterns, no banned words. Use simple narrative style, with specifics, case studies, etc. No headings, no title. Just paragraphs.

We must avoid banned words: "、总的来说、让我们...、。当传统渠道的流量逐渐见顶，越来越多的中小企业发现，一款既美观又高效的官网已成为品牌塑造的关键。于是，‘上海公司网站建设，专业定制助力企业品牌升级’这个词组自然浮现在视野中，成了许多决策者手中参考。"

That's about 182 characters. Need 150-250, so okay it's within range. Actually it's 182, okay. Good.

Paragraph 2: talk about why website matters for brand upgrade. Need 150-250 characters.

"一个专业的网站不仅是企业的数字名片，更是展示产品细节、传递企业文化的舞台。通过精准的页面布局和互动设计，用户可以在几秒钟内感受到品牌的专业度和独特性。举例来说，一家上海的家居企业在改版后，将产品线以视频方式呈现，访客停留时间提升了40%，咨询转化率也随之增长。这样的案例说明，网站的内容与结构直接影响品牌在消费者心中的印象。"

Count characters roughly: Let's count quickly approximate: "一个专业的网站不仅是企业的数字名片，更是展示产品细节、传递企业文化的舞台。通过精准的页面布局和互动设计，用户可以在几秒钟内感受到品牌的专业度和独特性。举例来说，一家上海的家居企业在改版后，将产品线以视频方式呈现，访客停留时间提升了40%，咨询转化率也随之增长。这样的案例说明，网站的内容与结构直接影响品牌在消费者心中的印象。" That's likely around 250 characters. Good.

Paragraph 3: talk about customization process, UI/UX, design.

"定制化的网站建设从需求访谈开始，设计师会先深入了解企业的业务模式和目标受众。随后在草图阶段确定信息架构，确保导航简洁直观。随后进入视觉设计环节，配色、字体和图形元素都经过多轮打磨，力求在视觉上与品牌调性高度统一。整个过程离不开跨部门的协作，产品经理、开发人员与运营团队共同把握每一个细节，使最终呈现的页面既美观又具备商业转化功能。"

Count characters: probably around 230.

Paragraph 4: talk about technical aspects: performance, SEO, security, mobile.

"在用户体验愈发关键的今天，网站的加载速度、移动端适配度以及安全防护都直接关联到品牌的信任度。
