《新唐书·列传·卷四十九》
武后又诏令去幽州审查都督屈突仲翔。宋瞡推辞说 ：御史中丞非大事不出使，仲翔罪仅止赃污，现在派臣去，这一定有人危害我。 
又诏按幽州都督屈突仲翔，辞曰： 御史中丞非大事不出使。仲翔罪止赃，今使臣往，此必有危臣者。 
The empress then ordered him to go to Youzhou to investigate the military governor Qu Tufeng. Song Kong declined the order, saying The junior minister of the Office of Censors should not go out on missions unless it is a serious matter. Qu Tufeng’s offense is no more than embezzlement, and if I am sent, someone will definitely plot against me.
