On Japanese Prime Minister Shinzo Abe's visit to the Yasukuni war shrine: Letitia Wong - PM Abe said by paying respect to his ancestors it reminds him of the atrocities created by the war. That's a very logical and appropriate answer. Michael Zee - Why would Abe do a thing like that except to provoke the neighbours and justify what the Japanese did? Jiji Fukuyama - Honouring mass murderers? We should be ashamed! We killed millions in Manchuria! Shame on us. Shame on Japan. Patrick Shu Wing Lee - I have stopped going to Japan and avoided buying Japanese goods. Kevin George Floreno - What a foolish thing to do! The US should cut them loose and then we'll see how brave Japan is. On claims that Hong Kong's status as a container port will continue to decline: Alan Chau - HK has maintained one of the best geographical locations in China and Asia to make some money. No worry in medium term, if we work in harmony with mainland. Kofi Time - It just doesn't make sense to ship via HK when the Pearl River Delta has efficient ports. Why go through the border formalities and pay more to ship out of Hong Kong? The government can build more subsidised housing. Gordon Lamb - While new terminals must definitely be canned, don't hold your breath that the government will not be suckered into expansion at cost to the public purse (just like the white elephant of a cruise terminal)! And then the operators will want to develop the terminals into housing, without of course paying anything. On Hong Kong's new Air Quality Health Index with its smartphone app: Terry Yau - Almost pointless on reporting the existence of the app if nothing is done about the actual problem. Cory Pchajek - This can be a good tool in deciding where to do your distance running for the day. Mike Brooks - Big deal. How about just clean the air?
