The Agency and the Taiwan Yilan District Prosecutors Office jointly investigated the case of Mayor Li X of Sanshing Township, Yilan County, and others who designated specific vendors to win the Christmas lighting decoration project and the Spring Festival street scene decoration project. Li X received a cash bribe of NT$200,000 from the vendor for each project, for a total of NT$400,000, as consideration for the breach of duty. Subsequently, when the Sanshing Township Office handled the additional engineering for the Christmas lighting decoration project, Li X and the aforementioned designated vendor colluded to illegally subcontract the project into several small-scale procurement cases, approving payments in batches to benefit the vendor.

After the investigation was concluded, the prosecutor indicted Li X for suspicion of taking bribes by an act that belongs to the official duties, seeking unlawful gains in matters under his charge or supervision and other offenses under the Anti-Corruption Act.
