HuoJi Navigation Inc. operates xspdh. com, a website directory and resource navigation service that organizes links into categories for overseas Chinese users.

The site describes its listings as comprehensive, regularly updated, and free of harmful content, while clarifying that linked websites are independent and their content is not affiliated with the directory. Its categories include general website recommendations, online video links, navigation directories, lottery forums, novels, and useful software and online tools. The tools section points visitors to resources such as ebook and file searches, file conversion, image hosting, online photo editing, video and YouTube downloading, VPN services, domain and IP lookups, and network utilities.

The site also provides domain announcements and publication pages, and invites website owners to explore listing cooperation. HuoJi Navigation states that its servers are located in the western Pacific and that access is intended for overseas Chinese. It warns visitors to follow the laws and policies where they live and says the site is not suitable for anyone under 18
