  This study utilizes the double copy relation to derive on-shell gravity as
product of gauge fields in Anti-de Sitter(AdS)space. Comparing with its
corresponding conformal field theory (CFT) gauge field, we establish a unique
connection between CFT gauge field and another gauge field in on-shell AdS
space, and confirmed it as a strong-weak correspondence having associated
thermodynamic properties. Also, it provides gravity theory coupling to a tensor
field instead of a scalar field, to be more complex but perhaps more accurate.
