Postal parcels are mainly delivered through postal channels. 70 % of the packages in China's cross-border e-commerce export business are delivered through the postal system. Hongkong Post and Singapore Post are also common logistics methods for cross-border e-commerce sellers in China.
Advantages: The postal network basically covers the whole world and is wider than any other logistics channel. Since postal services are generally state-owned and have state tax subsidies, the price is lower.
