The episode describes "Grasp the Bird’s Tail" (or "Grasp the Sparrow’s Tail"), a fundamental Tai Chi Chuan movement sequence.

This sequence, also known as Lǎn Qùe Wěi, is composed of four essential parts: Ward Off (Peng), Roll Back (Lü), Press (Ji), and Push (An).

Each part involves specific energy manipulation, transitioning from defensive yielding to offensive redirection and ultimately controlling the opponent's balance.

Mastering this sequence provides a foundation for understanding key Tai Chi principles, such as using the waist and legs, and is considered crucial for learning more advanced techniques.

Its importance is highlighted by its presence in various Tai Chi forms, even constituting entire shorter forms in some cases.
