Chinese New Year (CNY), the most disruptive event in China, officially begins on February 5th, 2019. The rush, and subsequent slowdown, often much sooner than that depending on the facility.
Most businesses come to a standstill for the holidays as a flood of workers
to their home villages to be with their families. The Telegraph reported in 2017 that the country's authorities expected the nation to make around 2.5 billion trips by land, 356 million by rail, 58 million by plane and 43 million by sea during Chunyun (春运) — the world's largest annual human travel season.
And after the holidays, many workers stay home and don't return to their factories. General managers are left scrambling to find and train replacements. So even if the holiday itself is only 3 weeks long, companies can take nearly 2 whole months to return to pre-holiday production levels!
It doesn't have to be this way. If a factory plans its operations correctly and makes changes before and during CNY, it can quickly regain full production and be a stronger, leaner manufacturing machine.
