you can see that the era is "ming guo" and "ming guo qian", but the year number is still 2002 and 101, As in taiwan, the year base on the birth of Republic of China (AD 1911) is also very popular, so should display as "<ming guo> 91" and "<ming guo qian> 3911", so if era is "ming guo" or "ming guo qian", need another calendar support for tradition chinese.
