Perhaps you should try some spelling variations:
knowing about » known about, know about, knowing your
mind knowing » d knowing, me knowing, wind blowing
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang, wang yan
li zhang » _ zhang
yan guan » gan guan, yan yuan, yang guang
1 human » 2 human, 3 human

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

• Performing a fuzzy search may retrieve terms with similar spellings: li zhang ((((yang liang) OR (yang yang))) or (yan guan)) 1 human mind knowing about ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: li zhang ((((yang liang) OR (yang yang))) OR (yan guan)) 1 human mind knowing about ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "li zhang ((((yang liang) OR (yang yang))) or (yan guan)) 1 human mind knowing about ;*".
