According to the forecast of the State Post Office, more than 1.5 billion packages may be generated during the "Double Eleven" this year. It is estimated that the annual express delivery volume will reach 40 billion pieces. If calculated according to the population of 1.3 billion, that is equivalent to an average of more than 30 express deliveries per person.
