The Central and South China Liberation area is composed of what in 1949 were the provinces of Henan, Anhui, Jiangxi, Hunan, Guangdong, Guangxi and Hubei. See the map below, taken from the PRC catalogue.

There are 264 different stamps in this area according to the PRC stamp catalogue. The JPS lists 278 stamps, with a great number of varieties not covered in the PRC catalogue. Yang lists 237, Scott 142 (6L and 7L), and Gibbons 210.

Although this area is not widely collected outside of China, this is one of my favorite areas. The northern part was one of the main centers of Chinese civilization, a major part of it centered along the Yellow River valley. Cities in this area have served as the capitals of 13 different dynasties. Some of the world's most famous ceramics were made here (Ru Yao, Jun Yao, and some Ding Yao). Some claim man first started farming in the Neolithic era close by (Yangshuo culture). Today there is a huge population centered here, and it is a marvelous place to visit if you are headed to China. The southern part of this area is now the industrialized Pearl River Delta.

Notes

The Central and South China LAS stamps are pretty straightforward and easy to identify, unlike the East LAS.

You do have to be somewhat careful of the overprint illustrations in the Yang catalogue.

There are some missing stamps.

There are a number of varieties in the JPS that are not addressed in the PRC, primarily perforation and paper varieties. The JPS is much more thorough in these areas. If you are interested in paper and perforation varieties, I must suggest you get a copy of the JPS catalogue. But note that at the writing of this, it is now 20 plus years old (published in 1988).

I am sure there have been additions by now.
