Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
phase dann » phase das
one phase » die phase, one case, one page
dann bin » dong bin
yong jin » ying jin, song jin, yang jing
yang jin » yang jie, yang jun, ying jin
yang xi » yang yi, yang jui

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: one phase dann bin we ((((yong jin) OR (yang liang))) OR (yang jin)) ((yang xi) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one phase dann bin we ((((yong jin) or (yang liang))) or (yang jin)) ((yang xi) or (yang di)) ;*.
