The Lu star is Ursa Major, or, in traditional Chinese astronomy, the sixth star in the Wenchang cluster, and like the Fu star came to be personified. The Lu star is believed to be Zhang Xian who lived during the Later Shu dynasty. The character 'Lu' specifically refers to the salary of a government official. As such, the Lu star is the star of prosperity, rank, and influence.

The Lu star was also worshipped separately from the other two as the deity dictating one's success in the Imperial Examinations, and therefore success in the imperial bureaucracy. The Lu star is usually depicted in the dress of a mandarin.

The term Fu Lu Shou or Fulushou collectively refers to the concept of Good Fortune (Fu), Prosperity (Lu), and Longevity (Shou). This Taoist concept is thought to date back to the Ming Dynasty, when the Fu Star, Lu Star and Shou Star were considered to be personified deities of these attributes respectively. The term is commonly used in Chinese culture to denote the three attributes of a good life.
