The move is derived from the tieshankao (貼山靠, lit. "Applying Mountain Lean"), a technique used in Hakkyokuken/Bajiquan (八極拳, lit. "Eight Extremes Fist"). It is altered through changing the first hanzi/kanji from 貼 to 鉄 (otherwise, the original Japanese reading would be "Tenzankou", while the pinyin reading would be the same).
Executed by performing a Shoryuken motion? and pressing punch, Yun perform a crouching turn-step forward and charge-leans the opponent with back of his shoulder through applying explosive force.How far the turn-step travels, how much damage the attack does, and how much startup and recovery time the attack requires all depend on the strength of the punch button pressed: light punch turns on the spot and does the least damage, but executes and recovers almost instantaneously; heavy punch travels about two-thirds of the screen and does the most damage, but takes the longest to begin and recover; and medium punch is a balance between the two.
The EX Special version turns faster than light punch, travels the length of the screen, and hits twice for as much damage as the heavy punch version.
Each version of the attack can allow a projectile to pass safely overhead if timed correctly. The non-launching versions can be used as a pressuring frame trap or as a method of offensive reset, from which a player can either continue the attack (often via an on-hit cancel) or bait further reactions from the opponent. Likewise, the launching versions can also work for juggles.
- Several characters, including Miyako Arima (Melty Blood), Kirei Kotomine (Fate/Unlimited Codes), Akira Yuuki (Virtua Fighter), Bayonetta (Platinum Games' Bayonetta series) and even the Chinese historical figure Liu Bei (via his Knights of Valour 3 portrayal) all have their own versions of this technique in their respective games.
- Miyako's version is a command normal that can be followed with an upward punch similar to the end of Yun's You Hou attack. Akira's variant is a special attack that works similarly.
- Bayonetta herself also uses the technique as her forward throw in Super Smash Bros. for 3DS/Wii U.
- Marvel Comics superhero Iron Fist (in Ultimate Marvel vs. Capcom 3) has the same special move, dubbed as Wall of K'un-Lun.
- In the anime Blood Lad, Staz does his version of this move.
- This technique was also used as a tackling taijutsu move in the anime filler episodes of manga series Naruto, performed by Shino Aburame.
- Lu Xun's Dynasty Warriors portrayal also has a variation of this technique as of the seventh installment of the series, named the Volcano Smash AKA Kazankou (火山靠 Kazankou?, lit. Volcano Lean) used as his Musou II attack.
- Tekken's Julia Chang uses this same style of attack in Street Fighter X Tekken. Most noticeably as part of her Super Art.
