In China people leave the wrapping on everything, until it's way too late and it is disintegrating. I guess it is so things look "brand new" In restaurants, the little transparent plastic stickers on drinking glasses are carefully preserved. My office chair still has the plastic wrap on the legs which is now in tatters. It's like that kid from school, when you went to his house on the weekend they had all the furniture wrapped in plastic and if you wanted to watch the TV you had to sit on this sweaty plastic cover on the couch. squeek squeek.
In China it's like that with the cars. All the cars. Everywhere !
The stickers stay on until they rot off. These are all pretty new.
Everything, including the delivery stickers from the factory. Lookit my new car !
