Blessing of Man (Hand of Man, Renhou, Renhu, 人胡）is an incredibly lucky incidental win.
There are two common definitions depending on the variant.
By Mahjong Variant
Some New Style, some Guangdong Style, Taiwanese
A Non-East player has a valid hand after calling East's first discard. If East declares a Concealed Kong, Blessing of Man is cancelled.
Some New Style, Japanese Riichi, and some Guangdong Style
A player has a valid hand upon calling an opponent's first discard. If a prior call is made by any player, Blessing of Man is cancelled.
Some variants use the first group's definition for their variant's Blessing of Earth.
Japanese Riichi
Blessing of Man used to be commonly found in Riichi rulesets, but like Nagashi Mangan, has lost favor in tournament settings.
In rulesets that use it, it's worth either Mangan or Yakuman.
Guangdong Style
The definitions of Blessing of Man and Blessing of Earth seem to coincide with what region the ruleset is from. If it's from Taiwan, Blessing of Man uses the 1st definition. If it's from elsewhere, it uses the 2nd definition.
