Xi 'an BYD No.1 Factory is mainly responsible for the production and processing of Samsung mobile phones. If you go in, it is likely to be a mobile phone production line operator or a material porter.
BYD's second factory in Xi 'an is mainly responsible for the production of BYD series cars, and the whole production process is complicated. If 16 years old enters, there may be more operator positions.
Of course, no matter how many factories you work in BYD, or you don't have other skills or trained employees, most of them basically start as operators.
