hanh trang » thanh trung, canh tranh, hanh trinh
phat nhung » pha nhung, phai nhuong, thuat nhung
hien xanh » hien hanh, hien nhanh, chieu xanh
cong dan » cong san, cong tan, cong dong
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc hien xanh - ((hanh trung) or (hanh trang)) phat nhung ((cong dan) OR (huong dan)) toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - ((hanh trung) OR (hanh trang)) phat nhung ((cong dan) OR (huong dan)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((hanh trung) or (hanh trang)) phat nhung ((cong dan) OR (huong dan)) toan cau".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - ((hanh trung) or (hanh trang)) phat nhung ((cong dan) OR (huong dan)) toan cau*.
