I agree, it's very heartbreaking to see parents sacrifice living and working abroad just to provide financial support to their families. It's very hard to take care of someone that's not their relatives and yet receiving their attention and care while their own families are longing to see and spend time with them. There are many workers abroad that are being maltreated by their employers and must be given enough attention by the government. That's why they are considered heroes because they sacrifice their lives just to give their families' needs.
