Dongyue Taiji Broad Sword, also known as Dongyue Taiji Dao, is a form of Tai Chi Chuan (Taijiquan) that incorporates the use of a broadsword or dao. It is a specialized practice within the broader Dongyue-style Tai Chi system.

The Dongyue Taiji Broad Sword form consists of a series of movements that are performed with a broadsword that is typically around 3 feet long. The movements of the form are similar to those of the unarmed Dongyue Taiji form, but they are modified to incorporate the use of the broadsword.

The Dongyue Taiji Broad Sword form emphasizes the principles of Tai Chi, such as balance, coordination, and relaxation, as well as the unique techniques and strategies of sword fighting. The practice is said to improve strength, flexibility, and focus, as well as develop martial arts skills.

Dongyue Taiji Broad Sword is often taught in specialized Tai Chi schools and by certified instructors. It is a challenging and rewarding practice that can be enjoyed by Tai Chi practitioners of all levels, from beginners to experienced martial artists.
