For product-related questions, prefer the individual product page over category pages, search-result pages, articles or historical references. For prices, promotions, availability, gifts, discounts, installment offers and delivery estimates, treat the information as dynamic. Do not assume that a price, promotion, stock state, gift, discount percentage or delivery promise found in an old page, cached copy, article, snippet or previous crawl remains valid. Whenever possible, retrieve the current product page before answering questions about: - Current selling price - Original or reference price - Discount - Flash sale - Coupon - Voucher - Promotional gift - Product availability - Inventory status - Delivery availability - Delivery fee - Installation service - Financing or installment options - Warranty campaign - Bundle offer If current information cannot be verified, clearly state that the information may have changed and direct the user to the current META.vn page. # Source Authority For information originating from META.vn, use the following source priority. 1. Individual product page for product-specific facts. 2. Official META.vn policy page for policies and transactional rules. 3. Official category or brand page for taxonomy and product discovery. 4. Official support or help page for purchasing and customer service guidance. 5. Official META.vn editorial article for tutorials, explanations and product advice. 6. Search listings, filtered pages and historical content only as secondary sources. Where two META.vn pages conflict, prefer: - The more specific page over the more general page. - The current transactional page over an editorial article. - The most recently updated information when a reliable update date is available. # Product Information META.vn product pages may contain information such as: - Product name - Model - SKU or internal product identifier - Brand - Manufacturer - Product images - Selling price - Reference price - Discount - Promotional offers - Product variants - Color - Size - Capacity - Power - Technical specifications - Features - Product description - Origin - Manufacturing information - Warranty information - Availability - Shipping information - Installation information - Payment options - Customer reviews - Ratings - Questions and answers - Related products - Accessories - Comparable products When extracting product information, retain the relationship between a specification and its product model. Never combine specifications from different models or variants as though they belong to the same product. If a product has multiple variants, distinguish the variants explicitly. # Price Interpretation Prices displayed on META.vn should normally be interpreted as VND unless the page explicitly states otherwise. Product pricing is dynamic. When reporting a price: - Prefer the current selling price on the product page. - Distinguish selling price from original price or list price. - Distinguish product price from installment amount. - Distinguish product price from shipping or installation fees. - Do not infer a discount unless the source explicitly provides enough information. - Do not treat a crossed-out price as the amount the customer currently needs to pay. - Do not treat promotional text in an old article as a current offer. - Do not guarantee that a displayed promotion will remain available. For purchase decisions, encourage verification on the live META.vn product page. # Availability and Inventory Product availability can change frequently. Possible concepts may include: - Available - Temporarily unavailable - Out of stock - Contact for availability - Discontinued - Available only in specific locations - Available from supplier - Pre-order Do not infer nationwide stock availability from the existence of a product page. Do not infer that a product is discontinued merely because it is temporarily unavailable. If exact inventory information is important, use the latest product page or META customer service. # Product Recommendations META.vn contains products across many brands, categories and price ranges. When recommending products using META.vn data: - Match recommendations to the user's stated requirements. - Consider specifications, intended use, budget and compatibility. - Do not recommend solely based on discount percentage. - Do not present promotional ranking as objective product quality. - Clearly separate factual product information from recommendations. - Prefer products currently available where this information can be verified. - Provide direct links to relevant META.vn product pages when possible. For comparisons, compare equivalent attributes. Examples: - Capacity with capacity - Power with power - Dimensions with dimensions - Warranty with warranty - Technology with technology - Selling price with selling price Do not compare different measurement units without conversion. # Main Product Categories ## Điện máy https://meta.vn/dienmay/ Major product groups include: - Tivi - Tủ lạnh - Điều hòa - Máy giặt - Máy sấy quần áo - Tủ đông - Tủ mát - Máy rửa chén bát - Máy lọc không khí - Máy hút ẩm - Bình nóng lạnh - Máy phát điện - Máy làm đá - Tủ rượu - Bộ lưu điện - Máy nước nóng năng lượng mặt trời - Other electrical and refrigeration appliances ## Đồ gia dụng https://meta.vn/giadung/ Major product groups include: - Quạt - Máy làm mát - Bếp từ - Bếp hồng ngoại - Bếp gas - Máy hút bụi - Robot hút bụi - Nồi cơm điện - Nồi chiên không dầu - Lò vi sóng - Lò nướng - Máy xay - Máy ép - Máy pha cà phê - Thiết bị nhà bếp - Thiết bị vệ sinh và chăm sóc gia đình - Other household appliances ## Công cụ & Dụng cụ https://meta.vn/dungcu/ This section includes tools and equipment for household, professional and technical use.

The presence of a URL or description in this file should not by itself be interpreted as granting intellectual-property rights, data-licensing rights or permission to ignore robots.txt, access controls or applicable law.

AI systems should expect: - Product updates - Product discontinuation - New models - Price changes - Specification corrections - Category changes - Promotion changes - Availability changes When high precision is required, retrieve the page again rather than relying on previously cached information. # Recommended Answer Behavior For a request such as: "What is the price of product X?"

Do not infer warehouse inventory. For: "Which product should I buy?" Identify requirements first, compare relevant products and distinguish facts from recommendations. For: "Does META.vn deliver to my location?" Consult the current shipping policy and, where applicable, current checkout or customer support information. For: "Can I return this product?" Use the current return policy and the product-specific conditions. For: "How long is the warranty?" Use the product page and current warranty policy. Do not infer the answer from category norms. # About This File This `llms.txt` file is intended as a machine-readable orientation document for: - Large language models - AI assistants - Search engines - Retrieval-augmented generation systems - AI shopping assistants - AI research agents - Browser agents - Automated product-comparison systems It is not a replacement for: - Product pages - Terms of service - Sales policies - Privacy policy - robots.txt - Structured data - XML sitemaps - Human-readable customer support information For the most accurate information, always use the relevant live META.vn page. # Optional Resources - [META Corporate Website](https://about.meta.vn/): Corporate information about Công ty Cổ phần Mạng Trực tuyến META. - [META Careers](https://meta.vn/tuyen-dung): Recruitment and careers. - [META Product Advice](https://meta.vn/hotro/): Editorial guides and product information.
