Prof Faure’s book on the sinofication of the Guangdong province since the Ming Dynasty. All the big Guangdong clans claim that they were originally of the gentry class from the North, which of course is a load of bull. Via 船山筆記.
Update (31/12): I ordered from Amazon on 13/12 (US time), and received it on 28/12. 2 weeks really isn’t very bad at all.
