Perhaps you should try some spelling variations:
ngai zhong » ngai hang, gao zhong
longer do » longer _, longer a
hadi chua » hai chuan
zhong zhi » zhang zhi, hong ghi, zhong tai
chua yee » chua tee, chung yee
yee chan » yee shan, lee chang, see chap
long do » long d, long du, long ago

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: ((long do) OR (longer do)) hadi chua yee chan ngai zhong zhi ;~.
• Adding a wildcard symbol may retrieve word variants: ((long do) or (longer do)) hadi chua yee chan ngai zhong zhi ;*.
