Currently, Taichung city uses the Hanyu Pinyin system of romanization on roadsigns. Some signs, however, still retain older Wade-Giles and MPSII romanization. Further complicating matters, many signs are simply misspelled. Some counties and cities around the island use the alternative Tongyong Pinyin. To help clarify the situation, the Compass Magazine map includes all three romanization systems for major roads.
