thanh vi » hanh vi, thanh va, thanh ve
duc manh » suc manh, duc anh, duc minh
va cham » va chat, va tham
ly nang » ky nang, ly hang, ly vang
vi cua » vai cua, di cua
cua te » cua tu
y nang » ky nang, v nang, may nang
va cam » va cac, va cao, va cai

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ((y nang) OR (ly nang)) xa hoi. lieu ((va cam) or (va cham)) duc manh thanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ((y nang) OR (ly nang)) xa hoi. lieu ((va cam) OR (va cham)) duc manh thanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ((y nang) OR (ly nang)) xa hoi. lieu ((va cam) or (va cham)) duc manh thanh vi cua te*".
