Family background: mainly to understand the relationship between relatives and friends at home, mainly the relationship between relatives and you, as well as their jobs, and the relationship between them and so on. If you use this aspect to affect your life, many enterprises value it, especially state-owned companies. I remember interviewing a state-owned enterprise before, and I particularly emphasized that this background should be clearly written. In fact, this is a place where they can use each other, and it depends on how many family members you have, your sense of responsibility and your burden. Personally, I feel this way. As for the later vocational qualification certificate, this is a side reflection of ability. You may not have this ability if you get a certificate, but someone with this ability will definitely get this certificate, so there is no harm in getting more certificates, such as accounting certificate and intermediate electrician certificate. If you work in the mechanical industry, you have mechanical engineer certificates, process engineers and many certificates, the more the better. Of course, you should also be useful to yourself. In fact, when you wrote about family education, your background was a little similar, but you wrote this information separately through family education, background and so on ... For example, the overall quality of your family can tell you, which is also a side reflection of your current state ... In fact, no matter what you fill in.
