   • 2014 September 15, Martin Gayford, “There's more to Ming than a vase [print version: 16 August 2014, pp. R6–R7]”, in The Daily Telegraph (Review)‎:

     The fact that the Yongle emperor was therefore a usurper, regicide and nepoticide (nephew-killer) made compiling the Veritable Record – or official history – of his reign a most dangerous scholarly post. The official given this ticklish task managed to survive several drafts, finally producing one that pleased his master as it omitted the dead nephew's reign altogether.
