va xanh » va hanh, va anh, va banh
te sach » toc sach
lam loc » lam duoc, lam ngoc
va lam » van lam, va lap
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang
di tu » dai tu, de tu, do tu

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 (v nang)) xa hoi. lieu va lam loc ((va xanh) or (va danh)) di tu tieng~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (v nang)) xa hoi. lieu va lam loc ((va xanh) OR (va danh)) di tu tieng.
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) or (v nang)) xa hoi. lieu va lam loc ((va xanh) or (va danh)) di tu tieng*.
