I came here after reading your #SarapPeroHealthy post.
Hmm, it's not an easy decision to make and both have different effects..

If you're going to quit and return home,
.. Being with your family, so no more homesickness and you will be there for your children growing up
.. Your passion so you're more dedicated to this
.. Do you have enough savings to keep afloat? Let's say worse scenario, your business if not doing well or not gaining profit, will your family still be able to pay bills and put food on the table?

If you're going to stay in HK,
.. How long are your planning to stay? If you stay, can you endure another 2 years being away from your family? Can you save in those 2 years?
.. Not your passion, but only just as a means of livelihood

I wanted to say follow your heart, but I think it's better to ask guidance from the Lord (sorry for being religious all of a sudden). Sometimes, whatever we desire, it might not be given because God has better plans for us. So pray for it, and maybe the Lord will guide you.

But if I were to decide for you, since I can see you're so passionate about cooking, I think you should focus on that. 🙏
