Not reliable. Chengdu Mi-speed supply chain is unreliable in running freight, and most of them sell trucks. Many warehousing and logistics companies and supply chains basically cooperate with various automobile suppliers. The advertisement that a car-free driver earns over 10,000 yuan a month is false. Supply chain companies recruit drivers with high salaries. Without cars, they can buy and supply cars. The fixed freight line mentioned at the beginning is full of goods and high in price, which is all fake.
