As the ruler of China, the First Emperor ordered great undertakings: his men put together earlier bits into a Great Wall of China and made a new river—the Lingqu Canal—so that boats were able to go from the Yangtze River in the middle of China to the Pearl River in the south. He ordered a large number of new roads and a tomb (last resting place) for himself the size of a city. This resting place was looked after by the thousands of statues of the Terracotta Army. Many people did not like doing as the First Emperor ordered: Sima Qian wrote about three men who made attempts to kill the First Emperor. All three came to nothing.
