金沙江是川藏的界河，以江心线为界。大桥有新旧两座，两桥相距几百米。桥上有分界标志。桥两头都有武警把守，严禁照相，西藏一侧需要检查身份证。正好遇到拉物资的军车车队，呆呆的望着车窗里笑，里面不时的伸出大拇指和加油的口号！
The border between Sichuan and the Tibet Autonomous Region is the Jinsha River, the actual boundary line is in the middle of the river. There are two bridges just a few hundred meters away from each other, one old and one new. On the bridge there are flags along the dividing line, at each end the bridges are guarded by People’s Armed Police, you aren’t allowed to take pictures of them, on the Tibet Autonomous Region side they need to check your ID card. Laughing as I look blankly out the window, giving a thumbs up and saying “Let’s go!” from time to time inside the car.
