Haircutting exemplified Chinese/Buddhist cultural problems. Buddhist tonsure required monks to shave their heads – but Confucian filial piety prohibited Chinese adults from cutting their hair (because it was ultimately a gift from one's parents). In Article 9, "Filial Piety and Buddhist Practice", the interlocutor quotes the "Classic of Filial Piety", as does Master Mou along with the "Analects".
