Hanyu Pinyin was invented in China and was accepted by the UN in 1986 as a standardized Mandarin Romanization system, whereas the Tongyong Pinyin system was designed by Yu Po-chuan (余伯泉), a researcher at Academia Sinica, in accordance with international phonetics and the Taiwanese method for Romanizing Chinese.
The main difference between the two systems is that the Tong-yong system uses a lot of local words and languages.
This, say some experts, can cause even more confusion for foreigners.
