Oriental rugs generally represent extremely good value for money. The decision to buy a Chinese rug, as opposed to a Persian or Turkish one, for example, should be based on a combination of an affinity with the general character of Chinese rug, and whether or not they represent value for money in comparison with other rugs on the market at the time.
However, one advantage that Chinese rugs have over rugs from other countries is their level of standardization and quality control; a prospective buyer can be certain that one 90-line Standard Chinese rug will, with very minor variations, be just as good as the text.
