Hakka people
The Hakka (), sometimes Hakka Han, are Han Chinese people whose ancestral homes are chiefly in the Hakka-speaking provincial areas of Guangdong, Fujian, Jiangxi, Guangxi, Sichuan, Hunan, Zhejiang, Hainan and Guizhou. The Chinese characters for "Hakka" () literally mean "guest families". Unlike other Han Chinese groups, the Hakkas are not named after a geographical region, e.g. a province, county or city, in China.

The "drapo servis" are important religious icons. 
They are kept in shrine rooms, and carried by flag bearers in elaborate ceremonies in the main chamber of the temple. A "drapo servis" will include an image of a Catholic saint or a "vèvè" (trace-work emblem) of an "lwa" (spirit) such as Papa Legba or Ogun of the Yoruba religion.
There are many "lwas", including Erzulie, Guédé, Damballa and La Sirene. 
The purpose of a ceremonial "drapo" is to flatter the "lwa" in the hope of gaining favor in return. 
Usually "drapo servis" are made in pairs, for example representing Ogun and Damballa.
Ogun was the "lwa" who led the slaves to freedom, and Damballa is the snake, representing the life force.
Ogun may be paired with other "lwas".
