luu van » cuu van, luan van, luu hanh
van cua » vang cua, ban cua, nan cua
dan cua » dan ca, ban cua, dai cua
y nang » ky nang, v nang, may nang

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y nang) OR (ly nang)) xa hoi. hieu ve cham luu van luan ((van cua) or (dan cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (ly nang)) xa hoi. hieu ve cham luu van luan ((van cua) OR (dan cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (ly nang)) xa hoi. hieu ve cham luu van luan ((van cua) or (dan cua)) tre*".
