Man.. Our factory is making a newly developed   medicine for cough. Through experimentation at   hospitals,  it's very effective and  now it's   marketable. But we must pay special attention to  the quality, though. Clearly, if the quality is   down the standard, something dangerous will   happen.  I hope everyone should be working   carefully at the machine, otherwise both the   patient and the factory will suffer lot.
