No, They are mostly back from 18th Feb. Of course there will be some guys coming back a lil later but they stagger the leave by a few days so some leave earlier.For the shipyard business, it’s not just 9 days. Because lots of workers come from different provinces, they will go back hometown and stay till the Lantern Festival, 15 days after CNY. Normally, the shipyard will be suspended for nearly 3 weeks.
There are also skeleton crew throughout the duration of the break but they can't do jack if weather don't suit painting conditions. They'll take however long it takes to get the coatings right.
