Perhaps you should try some spelling variations:
down planned » how planned, down planning, down land
planned how » planet how, planning how, planned what
hong down » ring down, holding down
ceo zhang » hao zhang
yeo chang » lee chang, po chang, woo chang
liang sun » liang dan, liang tan, wing sun

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: hong down planned how ((ceo zhang) OR (yeo chang)) jian ((cong shu) OR (liang sun)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hong down planned how ((ceo zhang) OR (yeo chang)) jian ((cong shu) or (liang sun)) ;~".
• Adding a wildcard symbol may retrieve word variants: hong down planned how ((ceo zhang) OR (yeo chang)) jian ((cong shu) or (liang sun)) ;*.
