Jason going overseas again

Dear is gg overseas again. This time gg Shanghai. I was thinking should i follow him but i have to spend money on the ticket...i dun have enough leave le hence if i really want to go, i have to take unpaid leave. Taking unpaid leave will affect my bonus. I really dont know should i go or not. Abit wasting money to go but it's an experience to go there now to experience winter. I also need to check with my new boss whether can i take leave during this crucial period cos we're doing budgetting. Hmm, should i go or not....
