I agree with MH for the most part. Stay away from the more "physical" aspects of Chinese culture. Eating snakes is not, and never was, a method of promoting health in the body. And as for the people who believe in eating rats, they are literally playing with life or death. Rats can be infected with bacteria that are very lethal if injested. They are more dangerous than chicken, which can also make you extremely ill.
But as far as the less physical aspects of Chinese beliefs, they are probably the most usefull of all cultures. Study the Kundalini meditation and Yoga exercise practices. These are actually very usefull to balance the body and maintain health. If you can, learn the Taiji and study how vital energy moves through the body. Although much of this is based on old mysticism, the effects are very real, and the old Chinese understood how it worked for the most part.
Just stay away from all the Chinese witchdoctor type stuff. Acupuncture is probably bogus, although I've never known anybody who actually tried it. Most dietary advice is also bogus, as the whole balance of yin/yang has been misrepresented by Chinese dietary theory. In fact, the yin/yang concept was based on old stereotypes, and was never really fleshed out very well. Some theories have some truth, but for the most part they are grasping at straws. This is because they assumed that the opposites were universal and general concepts. For example, they thought that heat/energy/masculine/sun/sky all represented an energy pole, but in reality this is not the case. All of these things are individual phenomena with their own opposites, and these individual principles were not all related, nor were they all present in foods. Thus, many of the old dietary beliefs were based on a theory that simply wasn't true.
