Taichung is a city with pleasant climate on the west coast of central Taiwan. The city is home to many manufacturers and in recent years has undergone a rapid growth of various cultural venues. Traffic in Taichung is better than in Kaohsiung or Taipei, though parking a car is still tricky. 

Taichung is relatively crime free compared to other cities of the same size, as long as you don't count overstaying a visa and working illegally as 'crimes'.
