Friend, let me tell you my personal opinion. It's really rare for you to have the opportunity to work in South Africa for two years. Think about it. If your relationship with your girlfriend is really sincere, these two years are not too much of a problem. The main reason is that you can't get several years of work experience abroad at home. It is a good opportunity to exercise yourself and test yourself. When the company wants to transfer people after returning to China in the future, you should also consider it first, even though you are suffering from illness. It is better to cherish this rare opportunity. If you lose it, it won't happen again.
