It is reported that China's Courier Service will deliver about 12 billion packages this year. Thus China might overtake the United States to become the world's largest express market. Most of the packages are filled with items purchased online. There are millions of online retailers in China and provide competitive prices to sell goods. Only on Nov. 11 one day, Chinese consumers spend $9 billion on the largest shopping platform of the nation. China has many such special shopping days, therefore, there is no wonder Courier Service can express quickly in China.
