Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yang wang » yang yang, yan wang, yang liang
wang yang » wang yan, wang liang, wang yanling
life cong » life long, life coming, life coping
wei yang » wei wang, wei yang's, wei shang
pei yang » hui yang, pei yun, yi yang

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 (wang yang))) or (yang guang)) ya hua ((wei yang) OR (pei yang)) life cong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang wang) OR (wang yang))) OR (yang guang)) ya hua ((wei yang) OR (pei yang)) life cong shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang wang) or (wang yang))) or (yang guang)) ya hua ((wei yang) OR (pei yang)) life cong shu ;".
• Adding a wildcard symbol may retrieve word variants: ((((yang wang) or (wang yang))) or (yang guang)) ya hua ((wei yang) OR (pei yang)) life cong shu ;*.
