Taipei's rat infestation problem continues to escalate, with DPP Taipei City Councilor Hsu Shu-hua criticizing the government today, saying that the problem should be addressed at its source, citing numerous expert suggestions, yet the Taipei City Government is still lagging behind. KMT City Councilor Liu Tsai-wei, on the other hand, believes that the DPP is using rats as a political tool in the election.
