In 2010, a free-to-download Three Kingdoms single-player game appeared on the internet. At that time, Chang Cheng-chou was studying at the Graduate Institute of History at National Chung Cheng University. Because he was extremely passionate about history, he participated in the playtesting of this game. During the playtesting process, he felt that the game's historical and cultural content was not complete enough. Since history is rich in educational significance, he felt that perhaps education and video games could be integrated by supplementing information. Therefore, he took the initiative to contact the game's creator via email. After contacting each other, the two decided to cooperate; the game creator was responsible for writing the game and programming, while he was responsible for continuously supplementing historical figures and events. After receiving a very enthusiastic response and numerous media interviews and reports, he eventually started his own business under the encouragement of his friends, founding 「河洛數位有限公司」.
