te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
xuc van » luc van, xuc ban, thuc van
duc van » duc va, duc tan, duc manh
ve cua » le cua, de cua, te cua

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 ky nang xa hoi. hieu ((qua cac) or (cua cac)) ((xuc van) OR (duc van)) thanh ve cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ((qua cac) OR (cua cac)) ((xuc van) OR (duc van)) thanh ve cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ((qua cac) or (cua cac)) ((xuc van) OR (duc van)) thanh ve cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. hieu ((qua cac) or (cua cac)) ((xuc van) OR (duc van)) thanh ve cua triet*.
