What is the treatment of Wuxi Nikon optics and operators? Don't tell me it's poisonous. It seems that few units in the new area are non-toxic. Please give a good answer and offer a reward of 10.

Mainly in four departments, 1 lens department, 2 lens barrel department, 3 camera department, 4 shaping department, and lens department is the most poisonous. People have been suffering from leukemia and uremia, and the highest salary is exchanged for life. The lens barrel is the second poison, and the salary with methanol is ok. The camera department is not poisonous, but the overtime work is less, the salary is less, and people are more comfortable. Only the shaping department works overtime. The salary is also high, but it is not easy to be admitted to the general.
