1. DHL is fastest and not expensive ---- If no liquid, no brand item(such as Nike, LV, UGG) in the parcel, the parcel volume is not too big comparing to the weight.
DHL doesn't have weight limited for a parcel
2. EMS ---- If you have liquid or brand item or parcel volume is too big comparing to the weight.
3. China post air mail ---- If the parcel is very small(<500g), It's cheap to use this method. But it take a long shipping time
