The certificate of reinforcement foreman is civil foreman.

There is a specialized engineering training institution near Chang 'an Street in Laoshan Dongli Community, Shijingshan District, Beijing, with a high pass rate. Its name is sublimation training, and basically all kinds of employment certificates are available. I'll call you first to ask: 88977726.

This kind of textual research is relatively short and has not been studied for several years. Unless it is a full-time technical school, after graduation, only the diploma of this major and some related documents will be issued.

(Disclaimer: I have nothing to do with this training institution, for reference only)
