Perhaps you should try some spelling variations:
hien nhanh » hien hanh, thien thanh, tien thanh
hien xanh » hien hanh, chieu xanh, hien khanh
quan dang » quang dang, quan lang, tuan dang
quan dong » quang dong, quan long, quan hoang
van thanh » ban thanh, van tuan
thanh cau » thanh chau, thanh mau, nhanh cau
canh ban » can ban, canh dan, canh van
cong van » cong vang, cong san, song van

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 ((hien xanh) OR (hien nhanh)) - canh ban ((quan dang) OR (quan dong)) cong van thanh cau~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (hien nhanh)) - canh ban ((quan dang) or (quan dong)) cong van thanh cau*.
