Perhaps you should try some spelling variations:
hao zhang » xiao zhang, zhao zheng, ceo zhang
yan liang » yang liang, wang liang, you liang
liang sun » liang dan, liang tan, wing sun
wang dan » wang yan, wang ban, wang yidan
co zhang » ceo zhang, _ zhang, li zhang
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: ((wang dan) OR (long haul)) plans how ((co zhang) OR (hao zhang)) yan liang sun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) or (long haul)) plans how ((co zhang) OR (hao zhang)) yan liang sun ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang dan) or (long haul)) plans how ((co zhang) OR (hao zhang)) yan liang sun ;*.
