The patterns on some of the older Chinese carpets are often taken from the patterns of the porcelain painters and from silks. In some cases the patterns also show old religious symbols with distinguished dragon patterns. The symbols in these carpets occasionally have Taostic or Buddhistic origins.
On younger and newly manufactured carpets, a variety of different patterns occur, for example flowers and some typical Persian motifs. These carpets are made with machine spun wool, dyed with sun and wash proof chrome colours. A large part of the newer carpets are thick and compact due to the double warp that is used (two layers of threads) and the technique of the knots are [ ] asymmetrical.
