Perhaps you should try some spelling variations:
tdinh trong » trinh trong, chinh trong, sinh trong
chieu sang » chieu sach, chieu xanh, hieu lang
dinh trong » sinh trong, chinh trong, dinh thuong
hang cong » dang cong, hang nong, bang cong
ho chieu » theo chieu, hoc thieu, doi chieu
cong san » cong tac
san than » sang than, san thanh, ban than
than cap » khan cap, thanh lap, thanh cac
va hang » van hang, va nang, va lang

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: ho chieu sang - ((dinh trong) OR (tdinh trong)) va hang cong san than cap~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - ((dinh trong) or (tdinh trong)) va hang cong san than cap*.
