Finally I took the choice to stay. I grieved over the decison for nearly 2 weeks and even after I made it, there were few days that I am remorseful. That is a totally field changing work with another stable career advancement. The offer is quite good for a fresh graduate. In comparsion, too many options and chances would be happened for my current suituation.

I am still young, should I take a stable offer? On the other hand,  my strength is on that area? Will I be happy to stay for long? I really want to learn that skill?

I cannot tell til I am composed. I believe I made the right decision. At least, I have the chance to strive and enter my target area. Even the worst case, I am still young to restart again.
