lang yanling » wang yanling, wang yangming, zhang yunling
usigng dong » using long
yang chik » nong chik, wang chi
dong sign » dong sin, among sign, dong bin
yang his » yang xi, yang yi, yang jie

• Adding a wildcard symbol may retrieve word variants: lang yanling ((((yang his) OR (yang chik))) or (yang di)) cost savings usigng dong sign ;*.
