The official romanization system for Taiwanese Hokkien (Taigi) in Taiwan is known as Tâi-uân Tâi-gí Lô-má-jī Phing-im Hong-àn, often shortened to Tâi-lô. It is derived from Pe̍h-ōe-jī and since 2006 has been one of the phonetic notation systems officially promoted by Taiwan's Ministry of Education. The system is used in the MoE's Dictionary of Frequently-Used Taiwanese Taigi. Its main differences with Pe̍h-ōe-jī are that it uses ts tsh instead of ch chh, u instead of o in vowel combinations such as oa and oe, i instead of e in eng and ek, oo instead of o͘, and nn instead of ⁿ.
