Tai Chi is primarily practiced as a martial art for health, meditation, and self-cultivation rather than as a combat-focused martial art. As a result, Tai Chi forms typically do not emphasize the use of traditional weapons. However, some Tai Chi styles and lineages may incorporate the use of weapons as part of their training curriculum. The most commonly used weapons in Tai Chi include:

1. Jian (Straight Sword): The Jian is a traditional Chinese straight sword with a double-edged blade. It is typically used in Tai Chi Jian forms, where practitioners learn to perform flowing movements with precision and grace while wielding the sword.
2. Dao (Broadsword): The Dao is a single-edged Chinese saber or broadsword. Some Tai Chi styles incorporate Dao forms, which involve fluid movements and techniques specific to the broadsword.
3. Qiang (Spear): The Qiang is a Chinese spear with a long shaft and a pointed blade at the end. While less common, certain Tai Chi styles may include Qiang forms that integrate the techniques and principles of Tai Chi with the spear.
4. Staff (Gun or Bang): The staff is a long wooden pole that can be used for training purposes. Although not strictly considered a weapon, staff forms may be practiced in Tai Chi to develop strength, coordination, and body alignment.

It's important to note that the practice of weapon forms in Tai Chi is typically an advanced level of training and is often viewed as an extension of the empty-hand forms. The primary focus of Tai Chi remains on cultivating internal energy, balance, and relaxation, even when incorporating weapons into the practice.
