For example, it is stipulated in the "Law on Election and Recall of Public Officials" that campaign expenditures must be reported, and cannot exceed a certain level (I think about NT $ 7 million for Taipei City [from where Chen was elected to the Legislative Yuan]).
像「選罷法」中規定競選經費要申報，而且不能超過某一個上限（台北市平均是七百多萬）。
