Perhaps you should try some spelling variations:
nhung chong » nhung cong, nhung phong, nhung phuong
hoc thieu » hoc hien
ctinh cua » chinh cua, sinh cua, trinh cua
chong van » thong van, hong van, phong van
tinh cua » trinh cua, sinh cua, tinh chat
van toan » van tuan, van tan, van thanh
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: ((hoc thieu) OR (toc thieu)) xanh - hanh ((ctinh cua) OR (tinh cua)) nhung chong van toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) xanh - hanh ((ctinh cua) or (tinh cua)) nhung chong van toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (toc thieu)) xanh - hanh ((ctinh cua) or (tinh cua)) nhung chong van toan cau*.
