It is a good test for the maintenance direction of Chengdu intermediate operators.

Nice test. The maintenance direction of operators of intermediate fire-fighting facilities is to maintain the safety of fire-fighting facilities and fire-fighting equipment. Chengdu intermediate operators' maintenance direction examination is repeated, and there is no problem in preparing for the exam, which is very good. Intermediate operators in Chengdu can engage in the operation, maintenance, repair, inspection, technical management and training of fire control facilities.
