"Right now, recruitment starts after the Spring Festival.According to media reports, given the feedback received at many large recruitment conferences, this year's "wanted-for-work shortage" of manufacturing and service industries, or the "universal labor shortage," is more worrying than ever.Some businessmen in Zhejiang say that this year's "harvest" is not so small, and that they are even facing a "grainless" situation.On one side are manufacturing, service, and universal labor shortages, with a large number of young people fleeing from traditional factories and assembly lines, while on the other hand, the average age of take-away workers is from 26 to 30 years, and nearly 70 percent of them are under 35 years old.According to the data, the number of out-of-town riders in 2015 was only 15,000, but by the fourth quarter of 2018, the number of active riders per day was close to 600,000, and the number of hive riders registered under the banner had already surpassed 3 million."
