+#### udp_over_stream
+
+This is the TUIC port of the [UDP over TCP protocol](/configuration/shared/udp-over-tcp), designed to provide a QUIC
+stream based UDP relay mode that TUIC does not provide. Since it is an add-on protocol, you will need to use sing-box or
+another program compatible with the protocol as a server.
+
+This mode has no positive effect in a proper UDP proxy scenario and should only be applied to relay streaming UDP
+traffic (basically QUIC streams).

+这是 TUIC 的 [UDP over TCP 协议](/configuration/shared/udp-over-tcp) 移植， 旨在提供 TUIC 不提供的 基于 QUIC 流的 UDP 中继模式。 由于它是一个附加协议，因此您需要使用 sing-box 或其他兼容的程序作为服务器。
