尊敬的用户与合作伙伴：
您好！
为进一步优化品牌形象、提升服务体验，实现公司业务的持续发展，西安瀚煜科技有限公司（以下简称 "我司"）将对官方网站域名及关联邮箱进行调整。在此，衷心感谢您长期以来的信任与支持，并就相关变更及风险提示，发布以下正式说明：
一、域名与邮箱变更核心信息
（一）原域名停用安排
已停用域名（请勿访问）：
- xianhanyukeji.com
- xianhanyukeji.cn
自2025年10月1日零点起，我司原官方网站域名 "xianhanyukeji.com" 与 "xianhanyukeji.cn" 将正式停用。停用后，这两个域名将无法正常访问我司官网及相关服务，请勿再通过原域名尝试访问。
（二）原域名后缀邮箱同步失效
特别提醒：与原域名关联的邮箱（即 "xxx@xianhanyukeji.com""xxx@xianhanyukeji.cn" 后缀邮箱）将随域名停用同步失效，自2025年10月1日零点起，该类邮箱将无法接收、发送邮件，也不再作为我司官方联络渠道。
（三）官方保留域名与邮箱（唯一有效入口）
1. 官方网站域名
我司唯一认可并持续持有、管理的官方网站域名如下，后续所有业务信息查询、服务对接、资料下载等均通过以下域名进行：
新域名对应的网站内容、核心功能（如产品展示、合作咨询、用户服务等）及服务标准与原网站完全一致，同时我司会持续优化网站加载速度与操作体验，为您提供更高效、专业的服务支持。
2. 官方联络邮箱
后续如需通过邮箱与我司对接，请使用以下官方邮箱，原域名后缀邮箱的所有业务将迁移至新邮箱：
- Business@hanyukeji.com（商务合作）
- support@hanyukeji.com（技术支持）
二、重要风险提示（请重点关注）
原域名 "xianhanyukeji.com""xianhanyukeji.cn" 及关联后缀邮箱停用后，我司将不再持有、管理该域名与邮箱。随着时间推移，原域名可能被其他机构、个人注册使用，原邮箱也可能被第三方获取，其后续发布的信息、提供的服务、发送的邮件等，均与西安瀚煜科技有限公司无任何关联，不代表我司官方立场。
为保障您的信息安全、财产安全及合法权益，特此提醒：
• 请勿通过原域名访问任何网站，或在相关平台提交个人信息、业务数据、支付款项等；
• 请勿向原域名后缀邮箱发送任何涉密信息、业务文件，避免因信息泄露导致风险；
• 如发现非官方平台使用与我司相关的名称、标识、域名或邮箱，请勿轻信，避免因误信非官方渠道造成损失。
三、操作建议与联系方式
（一）操作建议
请您在2025年10月1日前，及时更新已保存的我司相关信息，包括但不限于：
1. 网站类：浏览器收藏夹、书签中的原域名链接，业务合作文档、内部系统中关联的原域名地址；
2. 邮箱类：联系人列表中我司原域名后缀邮箱，替换为官方新邮箱（Business@hanyukeji.com、support@hanyukeji.com）；
3. 设备类：个人电脑、手机等设备中记录的原域名、原邮箱信息。

A special reminder: Emails associated with the original domain names (i.e., emails with suffixes "xxx@xianhanyukeji.com" and "xxx@xianhanyukeji.cn") will become invalid simultaneously with the deactivation of the domain names. From 12:00 AM (midnight) on October 1, 2025, such emails will no longer be able to receive or send messages, nor will they serve as our company's official contact channels.

The website content, core functions (such as product display, cooperation consultation, and user services), and service standards corresponding to the new domain names are fully consistent with those of the original website. Meanwhile, our company will continue to optimize the website loading speed and operation experience to provide you with more efficient and professional service support.

II. Important Risk Warnings (Please Pay Close Attention)
After the deactivation of the original domain names "xianhanyukeji.com", "xianhanyukeji.cn", and the associated suffix emails, our company will no longer hold or manage these domain names and emails. Over time, the original domain names may be registered and used by other organizations or individuals, and the original emails may also be obtained by third parties. Any subsequent information released, services provided, or emails sent through them have no connection with Xi'an Hanyu Technology Co., Ltd. and do not represent our company's official position.
To protect your information security, property security, and legitimate rights and interests, we hereby remind you:
• Do not access any website via the original domain names or submit personal information, business data, or payment funds on related platforms;
• Do not send any confidential information or business documents to the original domain-suffix emails to avoid risks caused by information leakage;
• If you find any non-official platform using names, logos, domain names, or emails related to our company, do not trust them to prevent losses caused by believing in non-official channels.

Please update the saved information about our company in a timely manner before October 1, 2025, including but not limited to:
1. Website-related: Original domain name links in browser favorites and bookmarks, as well as original domain name addresses associated in business cooperation documents and internal systems;
