It seems that one consequence of Wang's reforms was a strong fall in the prices, i.e. a deflation; therefore, as soon as the first decrees were issued, the large plantation owners and the merchants who were allied to them, offered furious opposition. A group of officials and landlords who still had large properties in the vicinity of Loyang--at that time a quiet cultural centre--also joined them. Even some of Wang An-shih's former adherents came out against him. After a few years the emperor was no longer able to retain Wang An-shih and had to abandon the new policy. How really economic interests were here at issue may be seen from the fact that for many of the new decrees which were not directly concerned with economic affairs, such, for instance, as the reform of the examination system, Wang An-shih was strongly attacked though his opponents had themselves advocated them in the past and had no practical objection to offer to them. The contest, however, between the two groups was not over. The monopolistic landowners and their merchants had the upper hand from 1086 to 1102, but then the advocates of the policy represented by Wang again came into power for a short time. They had but little success to show, as they did not remain in power long enough and, owing to the strong opposition, they were never able to make their control really effective. Basically, both groups were against allowing the developing middle class and especially the merchants to gain too much freedom, and whatever freedom they in fact gained, came through extra-legal or illegal practices. A proverb of the time said "People hate their ruler as animals hate the net (of the hunter)". The basic laws of medieval times which had attempted to create stable social classes remained: down to the nineteenth century there were slaves, different classes of serfs or "commoners", and free burghers. Craftsmen remained under work obligation. Merchants were second-class people. Each class had to wear dresses of special colour and material, so that the social status of a person, even if he was not an official and thus recognizable by his insignia, was immediately clear when one saw him. The houses of different classes differed from one another by the type of tiles, the decorations of the doors and gates; the size of the main reception room of the house was prescribed and was kept small for all non-officials; and even size and form of the tombs was prescribed in detail for each class. Once a person had a certain privilege, he and his descendants even if they had lost their position in the bureaucracy, retained these privileges over generations. All burghers were admitted to the examinations and, thus, there was a certain social mobility allowed within the leading class of the society, and a new "small gentry" developed by this system.
