Now I have a full understanding of all the data. The user wants the demo/example data (post titles, captions, content, alert messages, script text, hashtags, KOC bios, etc.) to be in English since they're simulating real TT/IG/Reddit content. The UI labels (buttons, headers, column names) should stay in Chinese. I only need to update mock-data.ts since all pages consume data from there.

Now I need to update the trends page chart legend names (which reference data field names in Chinese) and the products page chart data keys:

The trends page has Chinese legend names like "Oversized 卫衣" and "工装机能" - I need to update those. The products page has Chinese chart data keys "趋势匹配" and "竞争指数". Let me fix both:

Now fix the products page chart data keys:

Now let me also check the alerts list and trending list components since they render mock data directly:

These components look fine -- they consume data from mock-data.ts which I've already updated. The UI labels ("热门品类 Top 5", "实时提醒") stay in Chinese, and the data content is now English. Everything is consistent.

已将所有示例数据（帖子标题、评论高频词、提醒内容、KOC名称/受众画像、脚本分镜文案、IG文案与标签、关键词、品类名、图表图例等）替换为英文，模拟真实的 TikTok / Instagram / Reddit 跨境电商营销场景。所有 UI 功能标签（页面标题、表头、按钮文字、筛选项等）保持中文不变。

Good, the mock data is already in English. Now let me check the remaining lines of mock-data and also check the inline data in the page components for any Chinese demo content:

Good, the mock data file is fully English. Now let me check the pages for any remaining inline Chinese demo data. Let me look for the monitoring page and other pages that may have inline data beyond mock-data imports:

Hmm, that regex doesn't work. Let me try a different approach:

OK so the Chinese text in the pages are all UI labels -- that's correct, the user only wants the demo data to be English. The UI labels should stay Chinese. Now back to the user's actual question: they want the monitoring page to clearly distinguish between weekly monitoring and monthly monitoring cycles, as shown in the architecture diagram ("周/月度 → 数据监测").

Let me now redesign the monitoring page to include weekly/monthly tabs with appropriate data views:

Now let me add weekly/monthly monitoring data to the mock data file and restructure the monitoring page:

Good, now I have full context. I need to:

1. Add weekly/monthly summary data and weekly/monthly report data to mock-data.ts
2. Redesign the monitoring page with a time-cycle switcher (weekly/monthly) and corresponding report views

Now let me rewrite the monitoring page with weekly/monthly cycle tabs:

数据监测页面现在通过顶部的「周度监测 / 月度监测」切换按钮，清晰区分了两种监测周期。周度报告展示日均互动量趋势（柱状+折线复合图）和各平台表现对比（进度条+关键指标），月度报告则展示各周表现趋势图和月度热词排行榜。两种周期各自有独立的报告摘要卡片（监测内容数、总互动量、平均互动率、新增爆款）和4个关键发现亮点卡片，下方保留原有的账号监控表和爆款内容卡片。
