that Jung Moo Kwan first used the term to refer to the art as well as introducing the symbol of the eagle to represent the art. Successor A direct student of Choi, Chinil Chang inherited the title of Doju in Choi's personal and complete system of Hapkido on January 15, 1985, becoming the second direct lineage Grandmaster. On April 5, 1985 Choi personally awarded Chang the only existing 10th Dan certificate in Hapkido history. Chang also had the privilege and honor of being the first Hapkido master awarded the 9th Dan certificate by Choi in 1980. A large inauguration ceremony followed on April 11, 1985. The historic event was covered and documented by Korea Sports News and MBC Korean Television. Choi Young-sool, Chang, and Choi's son, the late Choi Bok-Yeol, were in attendance. Chang is the only Hapkido master ever awarded the 10th Dan and Doju title directly from Choi.

Chang's intimate video interview(one of several over decades) with his teacher Doju Choi during his visit to New York City has been abused through numerous interpretations and translations. Some have even claimed erroneously to have conducted the interview themselves, further clouding and distorting the truth and gravity inherent in the interview. These endless distortions were generally rebutted in various media each time they appeared. In 2013, Doju Chang was teaching a small group in NYC dedicated to the preservation of Hapkido, after previously maintaining a commercial school for decades, as well as a stint teaching Hapkido at the United Nations. Many detractors have spread endless conjecture about him. One lineage created further controversy by stating Choi passed the system to his only son, Choi Bok-Yeol, which is incorrect, misleading, and insulting to the legacy and wishes of Choi. Black Belt Magazine, respecting Chinil Chang as the second lineage successor, asked
