The line selection of the Hong Kong server needs to be determined according to actual needs and target users. As an international financial and business center in Asia, Hong Kong has a well-developed Internet infrastructure, and major telecom operators and network service providers have nodes in Hong Kong. The following are some commonly used line options and the corresponding advantages:

1. Telecommunication lines:

Suitable for websites and apps that mainly target users in Mainland China, as the Hong Kong Telecom network is mainly provided by China Telecom. The advantage of telecommunication lines is that they are stable and reliable, and suitable for transmitting large amounts of data.

2. Unicom line:

Suitable for websites and applications that mainly target users in East China, where the China Unicom network is more developed. The advantage of China Unicom line is that it is fast and suitable for transferring small files.

3. Mobile line:

Suitable for websites and applications that primarily target mobile device users, due to the high penetration of mobile networks. The advantage of the mobile line is that it is suitable for transferring large files such as streaming media.

4. BGP line:

Suitable for global websites and applications because BGP circuits can provide global coverage. The advantage of the BGP line is that it is stable and reliable, but the cost is relatively high.

Comprehensive consideration, it is recommended to choose a Hong Kong server that supports multiple lines, so as to meet the needs of different target users. In addition, factors such as the network quality of the computer room where the server is located, the security of the computer room, and server configuration need to be considered.
