Perhaps you should try some spelling variations:
wang wei » zhang wei, wang zhi
wei aung » wei aun, wei guang, wei lun
aung win » aung san
win when » win win, can when, win even
doch ein » doch eine, noch ein, doch keine
yang jui » yang judy, yang yi
yang xi » yang yi
do ein » so ein

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: wang wei aung win when ((do ein) OR (doch ein)) ((yang jui) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang wei aung win when ((do ein) or (doch ein)) ((yang jui) or (((yang di) or (yang xi)))) ;*.
