What is the difference between the apprentice of sofa wagon and the apprentice of sofa fabric sofa, soft sofa and sofa bed?

There is basically no difference between a sofa wagon apprentice and a fabric sofa, a soft sofa apprentice and a sofa bed. The carriage apprentice is a bit complicated. It takes a little longer to learn. Sofabed is the simplest. It's good to learn to be a lathe worker on the sofa. Although the salary is low when studying, it doesn't include anything. But I learned that the guaranteed salary is at least 5000 yuan. I have been making sofas for many years. You can earn eight or nine thousand to more than ten thousand if you turn fast.
