Henri Mouhot,
Travels in the Central Parts of Indo-China…
“ Most of the Chinese merchants are addicted to gambling, and to the use of opium; but the Annamite Christians are better conducted. The nature of these Annamites is very different from that of the Siamese, who are an effeminate and indolent race, but liberal and hospitable, simple-minded, and without pride. The Annamites are short in stature, and thin, lively, and active; they are choleric and vindictive, and extremely proud; even among relations there is continual strife and jealousy. ”
