How much does the official designer of Lushun 48 10 shipyard deduct from five insurances and one gold?

Lushun 48 10 Shipyard is the largest military production unit in Lushun Naval Base (I heard that it was related to Li Hongzhang when I went there on business). The ships built are mainly military small destroyers, maritime patrol boats and some civilian ships. This shipyard is the first in Dalian, which is both a state-owned enterprise and a military enterprise. I was on a business trip at Waigaoqiao Shipyard, where I visited and studied 1 week. The annual salary of engineers there is 60,000-70,000 (including bonuses), which is indeed lower than that of our Waigaoqiao Shipyard, but it is the best treatment in Lushun, Dalian.
