Perhaps you should try some spelling variations:
wang liang » wang yang
yang wang » yang yang, yang guang, yang liang
liang hua » wang hua, liang sun, liang zhu
hua irene » hua ren
irene yan » irene a, ren yan
yan wang » yuan wang, yang yang, qian wang
hong yu » wong yue

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang wang) OR (yan wang))) or (wang liang)) liang hua irene yan (tan or than) hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang wang) OR (yan wang))) OR (wang liang)) liang hua irene yan (tan OR than) hong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang wang) OR (yan wang))) or (wang liang)) liang hua irene yan (tan or than) hong yu ;".
• Adding a wildcard symbol may retrieve word variants: ((((yang wang) OR (yan wang))) or (wang liang)) liang hua irene yan (tan or than) hong yu ;*.
