Hong Kong's political uncertainties, fears of assimilation into the mainland, and annoyance about how things are going on many levels, have led some local residents to consider upping sticks and moving elsewhere. Although this is seldom discussed in public it turns out that for some, Taiwan is the destination of choice for a number of Hong Kongers. Over the past few weeks, the simmering resentment over the behaviour of some mainland tourists and their children has risen to a new level of hostility. Meanwhile mainland media and websites have been arguing that it's Hong Kongers who are in the wrong for being so offended. But look at some of the videos on the internet and it's clear that people in some of the mainland's own cities are just as offended by inappropriate behaviour. With us in the studio to discuss the clash of values is sociologist Cheris Chan from the University of Hong Kong. Deacons law firm has donated a treasure trove of archival material to the University of Hong Kong. Much of it dates back to Hong Kong's old opium dealing days, and is likely to prove invaluable to future writers and historians.
