Perhaps you should try some spelling variations:
knowing about » known about, know about, knowing your
from knowing » from known, from king, from closing
huang ying » huang jing, huang ting, huang yang
wang yang » wang yan, wang liang, wang yanling
king from » kings from, kong from, making from
1 king » _ king

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 yang) OR (huang ying)) ((zhang wei) OR (zhen wei)) 1 king from knowing about ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (huang ying)) ((zhang wei) OR (zhen wei)) 1 king from knowing about ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (huang ying)) ((zhang wei) OR (zhen wei)) 1 king from knowing about ;*.
