Visa question from a Volunteer for 5 months from Hong Kong

Hi, I'm from Hong Kong, part of China but different, looking for the opportunities to volunteer in Bolivia. I doubt if helping at an eco-village counts as "volunteer work", although i will not be making a profit.

Is the specific purpose visa required for the period around 4-6 months? Since the visa region I belonged to is Group 3.
