You're right. The contents of The Complete Works are exactly the same as those in the three volumes, except that the Complete Works are better packaged and a DVD of Baliren's Meridian Health Preservation is brought. The DVD answers your common questions, and some models demonstrate common health-keeping methods, such as three-step blood drawing and four health-keeping methods on the floor. It feels good. There are two CDs of "Looking for a doctor is better than looking for yourself", and the content is similar to the above. You can find many such CDs on the Internet, such as/playlist _ show/ID _1406975.html. Personally, I mainly want to accept the health concept of the Chinese science teacher. Of course, many of the methods he talked about are simple, and if I stick to them, it should have good results. Big books have some gifts, such as scraping boards and shiatsu sticks, which are also more expensive. Of course, you can also buy it yourself.

If it's just for your own use, buy three. A great collection is also good. CDs can be viewed online. Personally, I think the complete works and large collections are biased towards giving books.
