'''Haitei raoyue''' {{kana|海底撈月}} or simply '''Haitei''' is a standard [[yaku]], where a player wins with the tsumo on the '''haiteihai''', the last drawable tile from the live wall.  As such, this yaku is only accessible via tsumo.  

The last tile draw and discard is defined by the [[dead wall]].  By rule, the dead wall must retain 14-tiles at all times; and this includes any revealed [[dora|dora indicators]].  Naturally, to score either haitei or houtei, a player must be at [[tenpai]] at the end of the hand just before [[ryuukyoku]]. Finally, hands may definitely be declared for a win, if either haitei or houtei is the only yaku of the hand.

== Haiteihai and houteihai ==

'''Haiteihai''' {{kana|海底牌}} is the very last tile that can be drawn from the regular wall.  This is clearly indicated as the 15th tile left, counting the tiles of the dead wall including the [[dora|dora indicator]].  Typically, this tile resides as the lower of two tiles next to the back end of the dead wall.  Earlier calls for [[kan]] may "alter" the designation of the last tile, as that same bottom tile gets shifted into the dead wall to maintain fourteen tiles after the [[rinshan]] draw. In some groups, the tile may physically be moved from the live wall into the dead wall to make it clearer when the hand ends, but this generally not done in advanced play.

 

 

If a player calls a kan when there is only one tile left in the live wall, the rinshanpai will be the last draw of the game. In this situation, the rinshanpai is not considered to be the haiteihai, and if the player calling kan wins off of that tile, it will be eligible only for the [[rinshan kaihou]] yaku and not for haitei. The final discarded tile is, however, considered to be the houteihai and is subject to the same rules as normal, including the prohibition on tile calls and the eligibility for the houtei yaku.

 

A player cannot call a kan after drawing the last tile (either normally or as a result of a kan), because they would need to draw a rinshanpai and doing so would bring the dead wall down to 13 tiles.

 

 

 

Haitei and houtei are mutually exclusive with each other, with [[chankan]], and with [[rinshan kaihou]].  Each of these yaku requires the winning tile to come from a different location (the live wall, a tile added to make a [[shouminkan]], and the dead wall, respectively).  Houtei cannot combine with [[mentsumo]] because it is only winnable via discards.

 

 

 

 

 

The term '''haitei raoyue''' translates literally as "scooping up the reflection of the moon from the bottom of the sea." It is a figurative Chinese expression (sometimes used in Japanese as well) use to mean a futile task. '''houtei raoyui''' is a pun on this, translating literally as "catching fish from the bottom of the river." The kanji 河 is the term ''[[kawa]]'', meaning the discard pond. Hence houtei is a pun referring to both haitei, and the act of catching a fish from the bottom of the discard river.
