Is the number of cargo passes approved by the state?

The data link is recognized by the state, and the data link system is mainly used to optimize and upgrade the stock service industry. Establish a big data system for stock products. Collect a large number of national inventory product data information, so that both supply and demand sides have enough product choices. This requires the establishment of an open and reasonable big data platform, so that the owners of inventory products are very convenient and willing to share product information. The goods ordering system is a property big data system, which collects the national stock property big data through online e-shop and offline goods ordering outlets, and can input the supply and demand property information online and offline, saving time and effort. It should be noted that in the data link system, there are only numbers representing the attributes of an item, and there is no "virtual currency"!
