Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
hoc thieu » toc thieu, hoc hien
truong va » truong dai, truong cao, truong dao
lang cong » dang cong, bang cong, hang cong
ho chieu » theo chieu, doi chieu, mot chieu
tung va » trung va, tuong va, dung va
san cao » san co, san cho, san bao

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) OR (hoc thieu)) sang - thanh ((tung va) OR (truong va)) lang cong thanh san cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) sang - thanh ((tung va) or (truong va)) lang cong thanh san cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) sang - thanh ((tung va) or (truong va)) lang cong thanh san cao*.
