A managed stream fishery on the Fanqi road (X004) in the Huairou mountains north of Beijing, fed by cold spring water. It stocks rainbow, golden rainbow, char and brown trout into a narrow, very clear channel, and it is one of the few waters in China where fly fishing is not merely tolerated but named in the venue's own published rules. There are bank positions and wading positions, a beginner-friendly stretch and a finer, more technical one, roughly 37km from the Huairou toll gate on the Jingcheng expressway. Its sister water, Liuli Xigu 琉璃溪谷, lies over the hill in Liulimiao and fishes rather differently. / 鳟鱼季管理钓场位于北京怀柔山区范崎路（X004）沿线，由山泉水补给。场内放养虹鳟、金鳟、红点鲑与褐鳟，河道狭窄清澈。这里是国内少数在自身规则中明确允许飞蝇钓法的钓场之一，设有岸钓位与涉水钓位，兼具新手区与精细钓区，距京承高速怀柔收费站约37公里。姊妹钓场琉璃溪谷位于琉璃庙，风格与此不同。
A narrow spring-fed channel in the granite hills north of Beijing, running clear and cold enough that the water sits near fifteen degrees while the air above it reads seventeen. The banks are close, the casting is short, and the mountains keep the summer out of it. / 北京北部花岗岩山区中的一条狭窄山泉溪流，水质清澈冰凉，气温十七度时水温仅约十五度。两岸逼仄，抛投距离有限，群山把暑气挡在了外面。
Wading: Narrow channel, limited backcast room, cold spring water
