By 413, Liu Bobo finally resolved to build a capital—one that he wanted to make absolutely impenetrable. He commissioned his cruel general Chigan Ali (叱干阿利) as the chief architect of the capital, which he named Tongwan—because, as he stated, he wanted to unite China and be the lord of 10,000 states. ("Tong" means "unite," while "wan" means 10,000.) Chigan ordered that the soil used in constructing the wall be steamed, so that it would be hardened and difficult to attack, and he often tested the walls during its construction; if an iron wedge were able to insert even one inch deep into the wall, the workmen who were in charge of that section of wall would be executed, and their bodies would be stuffed into the wall. Further, Liu Bobo himself ordered that when weapons and armors are made, that some of the metalsmiths would be executed—because his orders were, for example, that arrows should be shot at armors; if the arrows could penetrate the armors, the smiths who forged the armors would be executed, and if the arrows could not penetrate the armors, then the smiths who made the arrows would be executed. As a result of this bloodshed, however, Tongwan became a highly defensible city, and the weapons and armors that he had were all of exceedingly high quality.
