Today i finally make a decision that having a journey to Thailand in next half a month. It only cost me 350+790 = 1140 rmb. But it seems that i have to pay extra tip for tourguide of Thailand, about 40 -50 per day. It’s hard for me to make this decision for: 1) Maybe i will have some interview during this week. 2) There should be other extra expenses during the journey. 3) I have to send my passport to shanghai by post. 4) The time of departure is uncertainty.
