《资治通鉴·唐纪·唐纪三十六》
玄宗命令左右的人把肃宗扶起说： 因为你的请求，张流放到岭表，张均罪大，不可饶恕，你不要再为他求情了。 
上皇命左右扶上起，曰： 张垍为汝长流岭表，张均必不可活，汝更勿救！ 
Xuanzong ordered the people on the left and right to help Suzong up and said: At your request, Zhang was exiled to Lingbiao, Zhang Jun's crime is serious and cannot be forgiven, so don't ask for mercy for him.
