前言爲何秦國能完成戰國時代各諸侯國的統一呢?要回答這個問題並不容易。這是因爲成功的原因不止一個,許多原因是錯綜複雜地結合在一起的。但常被指出的一個重要原因是秦國的軍事力量。例如張儀是這樣描寫秦兵的戰況的:秦帶甲百餘萬,車千乘,騎萬匹,虎賁之士跿跔科頭貫頤奮戟者,至不可勝計。秦馬之良,戎兵之衆,探前趹後蹄閒三尋騰者,不可勝數。山東之士被甲蒙冑以會戰,秦人捐甲徒裼以趨敵,左挈人頭,右挾生虜。 Preface Why can Qin complete the reunification of vassal states during the Warring States Period? It is not easy to answer this question. This is because there are more than one reason for success, many of which are intricately combined. However, one of the important reasons that have often been pointed out is the military strength of the Qin state. For example, Zhang Yi is the description of Qin Bing’s battle conditions: Qin with more than a million, the car ride, ride a million horses, tiger Ben Shizuo Shi Yi Guan Yi Guan Yi Guan, never to win. Qin Ma of Liang, Rong Bing of the public, exploring the front and rear hoofs three casual players, countless. Shandong’s soldiers were Meng Meng to the battle, Qin people donated armor to fight the enemy, the left Xun head, the right relying on students.
