Perhaps you should try some spelling variations:
liang dan » liang tan, king dan, wang dan
zhang yan » zhang fan, zhang jian, wang yan
yan liang » yang liang, wang liang, you liang
liang sun » liang tan, wing sun
how ceos » how cios, how close, do ceos
how co » how cios, how cool, how core
haul » hall, paul, hail
plans » plan

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: ((liang dan) OR (long haul)) plans ((how co) OR (how ceos)) zhang yan liang sun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((liang dan) or (long haul)) plans ((how co) OR (how ceos)) zhang yan liang sun ;~".
• Adding a wildcard symbol may retrieve word variants: ((liang dan) or (long haul)) plans ((how co) OR (how ceos)) zhang yan liang sun ;*.
