In the article BitsFlow Hong Kong VPS Launch: 300Mbps Direct Connectivity, Native IPv4/IPv6 Support, Double Resources for ¥170/year, we introduced the launch of BitsFlow Hong Kong VPS. However, no detailed performance review was included at that time. This article provides a more in-depth evaluation of its actual performance (roughly: China Telecom CN2 outbound, China Unicom and China Mobile direct routing; return traffic for all three networks goes via China Mobile CMI direct route).

Below are the available Hong Kong VPS plans from the provider:

### Detailed Return Path Summary:

* China Telecom: Hong Kong → China Mobile CMI → Mainland
* China Unicom: Forced via China Mobile CMI → Mainland
* China Mobile: China Mobile CMI direct return

## Traceroute Results (Partial)

Below are representative traceroute results for China Telecom / China Unicom / China Mobile routes. The key observation is that most return paths converge at China Mobile CMI before entering mainland China networks.
