Perhaps you should try some spelling variations:
labor working » labor earning, about working, labor during
working long » working longer, working poor, working life
wang liang » wang yang
yan liang » yang liang, you liang, yan wang
long dong » long bond, jeng dong, long do
dong ping » dong sin, dong bin, dong jung
ii labor » ii labour, iii labor, ii libor

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((((yan liang) OR (wang liang))) OR (wang yan)) ii labor working long dong ping ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((((yan liang) OR (wang liang))) or (wang yan)) ii labor working long dong ping ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((((yan liang) OR (wang liang))) or (wang yan)) ii labor working long dong ping ;*.
