When did A Chinese Odyssey come out?

"A Chinese Odyssey onlineII" is an excellent RPG online game launched by Netease in June 2002, and its predecessor was "A Chinese Odyssey Online". In March, 20001year, Netease officially acquired Tianxia game, and based on Tianxia's technical team, based on China's classical romantic novel The Journey to the West and famous Hong Kong movies, it developed a new generation of Online game "A Chinese Odyssey Online" with exquisite antique China style, rich game connotation and good gameplay. However, at that time, there were serious bugs in "Big Story One", and there were no factors such as subsequent development and offline G, so that "Big Story One" was destroyed as soon as it came out. I may be just an experiment in my early boasting. After summing up valuable experience and lessons, Netease redeveloped "A Chinese Odyssey Online Ⅱ II" on the basis of the original boasting resources, and ended the internal testing and started the public beta in June 2002.
