目前中轉一般都是國内大帶寬VPS，配合翻墻有大幅度延遲降低+速度提升。綫路一般比較優質，例如你的VPS被墻了，但是可以通過中轉來使用。(Using high-bandwidth VPS in China's mainland as intermediaries may significantly reduce latency and increase speed while bypassing GFW.{The function of the intermediary VPS is traffic forwarding .} The routes are generally of great quality. We could still use our VPS through intermediary if our it gets block.)
原理：用戶 >> 中轉 >> 你的VPS (Mechanism: local -> intermediary -> VPS)
詳細點例如：用戶 >> 國内中轉入口 >> 國外出口 >> 你的VPS (In more detail, local -> intermediary inbound in China's mainland -> intermediary outbound oversea -> VPS)
我用的中轉是 happynewcloud，價格原先是月50￥/2000GB，現在漲價到70￥/月了。下單地址(Order link) (The traffic forwarding provider I'm using is happynewcloud and the cost has increased to 70CNY/mon 2000GB from 50CNY/mon 2000GB.)
