秦始皇统一后，为什么要统一文字？

Qin Shi Huang was the first emperor of China. 秦始皇是中国第一个皇帝。 Before him, six countries had different words. 那之前，六国的字都不一样。 People could not read each other's writing. 大家互相看不懂对方的字。 He made everyone use one kind of writing. 他让天下人都用同一种字。 That new writing was called small seal script. 这套新字叫小篆。 Now the whole country read the same words. 从此全国人读同一套字。
