But we won’t see Hsieh talking bad about Soong. We will only see him talking bad about Hau (I would personally distribute some Lafayette shopping bags).

I would even personally give the pins…
About the theme of these elections - which seems to be the Tamsui river, who is more capable of cleaning it? My belief is none.
Cleaning a river is not simply cleaning the water. The things you need are so extense that it would take a complete change in Taipei city and Taipei County. Last year the EPA allready announced a 3 year plan and NT$1 Billion to clean it up (plan approved by Frank Hsieh), so any mayor coming now to say that they have a miraculous plan can be relying on this EPA budget. Anyway, I would like any of the candidates approach a real ecologist foundation and ask for help from specialists. Harsh measures will have to be taken, and many people will suffer from it, but as long as the Tamsui river is as it is, Taipei citizens will have health concerns. So, what to do?
I would say first concentrate on the source of the pollution - waste water, rain water and direct sources of pollution (discharge of polluents in the river directly).
Waste water has to be 100% directed to sewage treatment stations, and the plan of building 7 of these by the EPA is a good one, but it should have been done in the 90’s.
Stormwater is a more serious problem. Because most people doesn’t know, the water from rain can introduce in the river extremelly dangerous pollutants, and the fact that most constructions in this area are not green nor thought to be green, added to the fact that it rains like hell over here, only increases this problem. Also, the fact that there are more buildings than trees over here makes the quantity of stormwater going into rivers a lot bigger. To solve it, we will need a lot of change in the way people live, do things, build things and think things. One can start with “green rooftops”, where the water that falls into them is directly sent to the drainage system - this not only avoids pollution, because rooftops are water collection baskets that stand higher, and therefore avoid needless contact of the water with sources of pollution, but also reduces the noise produced by the rain itself (and we all know how noisy it can be). Other inteligent thing to add to the rooftops are plants, which absorve water by themselves, reducing the quantity of drain water. Second, permable pavement allows better drainage flux and control, lowers the risk of flood and also lowers the contact time of water with rubber and pollutants from the traffic. Third, riparian protection allong the costs of the Taipei city rivers, allowing for life to be able to develop there (and not fill the sides of the river with carparks). Increasing the number of trees here will reduce the ammount of water running into the rivers, allowing a better flood protection and lowering the pollution effects of stormwater.
I could continue here, but for sure I made more clear then any candidate what needs to be done. Because, making promises everyone can make, but explaining how they will fullfill their promises is something different.
