why my parcel shows dispatching from 23rd of feb?

Arrey Beti, The status shows dispatching because it is still being prepared by the seller to go to next stage of shipping. Remember China-Post uses the least expensive shipping method. Unfortunately this also make it the slowest ever shipping method. I think that the shipper dovetails a whole lot of orders going to same location together before moving it further in the shipping process.

Usually it takes 7 – 20 working days for AIR and SAL mails, and 40 – 70 days for a surface mail. If there is any delay it could take as long as long as 180 days.
