Mengxia Zhang is a member of the Yellow Heads.
Mengxia and Yigao Wu come to get revenge on Ryo Hazuki for beating up the Yellow Heads that were terrorizing Guixiang Lee before. Guixiang instructs Ryo to perform the Hind Blow move on Mengxia. If he does so, or defeats him without performing the Hind Blow move, the two will cowardly flee. If Mengxia defeats Ryo, Guixiang will defeat him using the Hind Blow instead.
