Car maintenance is a well-known platform for trading spare parts for b2c cars in china, and the brands now have outlets in the first and second-tier cities of hangzhou and ningbo. Car maintenance began to transform into an industrial chain layout. After years of deep-croping, the car maintenance core group has served enterprises actively explored in the post-car market, such as zhejiang positive energy motors services ltd., zhejiang cars, daylight cars, and little thumbs, with a deep knowledge of the post-car service chain and the ability to move quickly. The transformational car-keeping system is based on a chain-based approach, taking into account the trend towards industrial development, actively promoting rapid transformational upgrading and the construction of new models, innovatively creating a system of member-based gas distribution services and a system of shared car repair services, creating efficient links from product manufacturing systems to warehouse distribution systems to service systems to consumers, and providing transparent services to garages and manufacturing plants. Car-keeping is based on the concept of "care for millions of car-owners without worries" and on the idea of "good, professional, secure" services, working together in the industrial chain to promote good industry。
