Ask an expert to give me a detailed analysis. Is the fitter better or the electrician? Is there a substantial difference between an advanced certificate and an intermediate certificate? Thank you.

At present, many factories and schools recruit senior locksmiths ... The salary is not bad ... If an electrician works, a company or manufacturer may recruit wiring and personal decoration of one or two management units ... The development prospect is not optimistic enough ... Personally, the certificate is only superficial. It may play a starting role in the interview. But now everything depends on strength and experience ... the so-called "specialization" means that some people will lose and some will win. As long as you choose a good goal, you must study harder than others, especially your peers. ..
