Did Zhang Qian escape from the Huns with a wife and a young son?

Bhurley, I didn't find any historical document that proves Zhang Qian got back with his wife and kids. It's said that his wife helped him escape. As a result, her arms were cut. However, Zhang Qian was caught. Zhang finally escaped again from the Huns after the Hun leader died. This time, his wife was shot to death by the Huns.
