Taiwan 4 months military service

Hello… New here… I’m a have filipino and half taiwanese. Currently staying here in Taiwan as a citizen. I was born here but grew up in the Philippines. I came back here in Taiwan hoping to learn mandarin… I realized that i still have to do the military service but since i was born in year 1994 they said i can do the 4 months service. I’m just wondering how was it? Need some idea about the training. Will it be hard if you’re mandarin wasn’t that good yet? And also i have a slip disk problem on my lower back. Is it gonna be a problem for me?
