Chang is a high-ranking admiral in the Chinese military who planned to overthrow the current Chinese government. He orders the assassination of Jin Jié, the future leader and voice for peace and progress in China. Despite failing, Chang was able to implicate the United States for Jié's death, and cancels elections whilst declaring martial law. This, in turn, causes both US and Russian navies to station themselves off the coast of China as political unrest increases and protests begin in Shanghai.[1]
Chang's character model

Whether by coincidence or not, Chang, in both the game and novel, appears only once during the protagonists' interrogation and torture scene.
Unlike other Chinese characters in Battlefield 4, Chang's name uses the Wade-Giles system of romanization instead of the Pinyin system. Chang Wei would be romanized as Zhāng Wěi in pinyin.
