Who has the instructor qq of Suihuaxin military training?

Sui Huaxin is not an army, but an expansion company. Instructors are not active soldiers, but wage earners recruited from the society. Of course, many of them are veterans. Their "military uniform" has no badge of the People's Liberation Army, let alone rank epaulettes and neckties, so they get some national flags and other patterns to decorate it. Their hats are more interesting. They designed a cap badge of their own, and dared not wear the August 1st cap badge of the People's Liberation Army at all.
