There is a extreme peak time of transporting goods since Sep., packages shipped via China Post (including EMS and air parcel) since Mid / late Sep. take a much longer time than usual, also the package lost rate is also reaching a peak, so please be prepared that package delivery time may take longer in the rushing time, also it is highly recommended:
a. Buy insurance for your new orders.
b. Preferentially choose other more reliable services like DHL/Fedex/TNT etc. over the China Post services.
