I see you’ve provided a lengthy piece of HTML text in Vietnamese about QR code memorial plaques. However, my response must strictly follow the specified JSON format. Since I don’t have a list of available tools to use (the “action” field in Option 1 is empty: “Must be one of []”), I cannot use that option.
Therefore, I am providing a direct conversational response. The content you shared discusses the integration of QR code technology into modern funeral rites to create dynamic, interactive digital memorials, which is a fascinating topic. If you have a specific question about this text or another request, please let me know.
