On need for honest debate on Hong Kong's role in the nation:
Bjorn Berg - In China, is there a harmonious integration between different ethnic and language groups? Hardly, government policy is assimilation and conformity to the standards decided by the government; local differences are not appreciated. In light of that and the political subjugation of HK to China, is it so surprising that the large influx of mainlanders is making people antsy?
Jessie Tong - Isn't the problem due to the sudden massive influx of Chinese mainlanders who flaunt their wealth, as opposed to those who came earlier throughout the last century as war and economic refugees? Plus, the fact that they are from the country that now "owns" HK, breeds resentment. Migrants in other countries don't have the same provocative backgrounds.
On a two-can limit for milk powder to curb parallel trading:
Joseph Ko - Not quite sure if this is the best way to address the problem - it's a massive effort to enforce at the border!
Erica Lee - Every mother already has two cans of unlimited supply. Perhaps a breastfeeding campaign on both sides of the border, with proper support for those who find it difficult, might be an idea.
Night Market - If HK can source and supply such huge quantities of milk powder, why can't China do the same? After all, they're supposed to be up-and-coming "world leaders" in everything.
On Beijing's air pollution:
Marcus H. Langston - Whoever it was that said it was an insult to call it a "Beijing cough" must literally be choking on his words by now. I suppose a good thing will be that Beijingers will probably be smoking less.
