Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
tran tuan » tran xuan, tran quang, tran thanh
cong tinh » cong trinh, cong vinh, long tinh
ho chieu » theo chieu, doi chieu, mot chieu
manh cua » doanh cua, ban cua
toan cau » toan cao, toan ban, toan tap

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 - hanh ((tran tuan) OR (manh cua)) nhung cong tinh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) sang - hanh ((tran tuan) or (manh cua)) nhung cong tinh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) sang - hanh ((tran tuan) or (manh cua)) nhung cong tinh toan cau*.
