wang yang » wang liang, wang yanling
che zhang » cheng zhang, zhen zhang, ceo zhang
zhang yan » zhang fan, zhang jian
cong days » long days, coding days, long day's

• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (wang yan))) or (yuan chang)) yang yi che zhang yan cong days ;*.
