Science and Health Service Center has been several times the phone said to come to my company voluntary training lectures, and is said not to charge any fees. And said it is a government agency!
The science and health service center has come to our company to do voluntary training, indeed free of charge. Most of the company's employees welcome the popular science knowledge in the lecture. Of course, the course last a small period of time is to promote a medical product, interested people can stay, not interested in people feel can leave, is not mandatory. However, I personally believe that this kind of science lectures are still worth listening to.
