Perhaps you should try some spelling variations:
hien nhanh » hien hanh, thien thanh, tien thanh
nhanh lang » nhanh quang, nhanh thang, nhan dang
den thanh » de thanh, dinh thanh, dong thanh
hanh mang » nhanh mang, hanh trang, thanh hang
luan dong » luan cong, quan dong, luan nong
dong cong » duong cong, dung cong, dang cong
cong van » cong vang, cong san, song van
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.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((hien nhanh) or (den thanh)) - ((hanh mang) OR (nhanh lang)) luan dong cong van toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien nhanh) OR (den thanh)) - ((hanh mang) OR (nhanh lang)) luan dong cong van toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien nhanh) or (den thanh)) - ((hanh mang) OR (nhanh lang)) luan dong cong van toan cau*".
