文王尊呂望（史記。文王為西伯時。一日夢飛熊之兆卜之。於渭水之陽。將大德焉。天與汝師以之佐昌齋三日。渭水果得呂望。勞而問之。乃載以歸。立為太公望）。

King Wen honored Lü Wang. (In the Records of the Grand Historian, when King Wen was the Western Earl, one day he had an omen in a dream of a flying bear. Divining it, [the oracle said that] on the north bank of the Wei River, there would be one of great virtue: 'Heaven grants you a teacher to assist Chang.' Having fasted for three days, at the Wei River he indeed obtained Lü Wang. Comforting and questioning him, he carried him back in his carriage and established him as Grand Duke Wang.)
