nong thong » nong thon, dong thong, cong thong
thong tran » thong than, thong tren, phuong tran
hien hanh » dieu hanh
hanh mang » hanh trang, nhanh lang, thanh hang
tran toan » tranh toan, tran tuan, tran tan
cua nong » cua cong, cuu nong, cua dong
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 ((kieu thanh) OR (hien hanh)) - ((hanh mang) OR (nhanh mang)) cua nong thong tran toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((kieu thanh) or (hien hanh)) - ((hanh mang) OR (nhanh mang)) cua nong thong tran toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((kieu thanh) or (hien hanh)) - ((hanh mang) OR (nhanh mang)) cua nong thong tran toan cau*.
