Is this information about going abroad for labor services true? Korea.

This is a lie. Hehe, in the past, the most expensive trainees did not exceed 50,000, and South Korea never had an E4 visa to work in a factory. Now E9 E7 is a specific visa, such as chef and waiter. Since 2007, South China has stopped importing labor. This is an agreement signed by two countries, so the Han people who go to Korea now are basically working illegally. The legal ones are students who came back in the past and turned against each other.
