thanh quan » thanh xuan, thanh tuan, nhanh quang
van khuan » van thuan, van huan, van khuon
quan doi » quan tri, quan li
van van » van ban, tan van, san van
kiem va » kien va, kiem tra, nhiem va

• If you are trying to use Boolean operators, they must be ALL CAPS: (( dinh van van khuan kiem va ) OR ( minh thanh quan doi phi va ))*.
