sach ty » sach y, sach tu, sach thu
tuc van » thuc van, truc van, tuc va
te sach » toc sach
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac

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 ty nang xa hoi. hieu ((ve cam) or (ve cac)) tuc van ((hanh lam) OR (hanh kem)) cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. hieu ((ve cam) OR (ve cac)) tuc van ((hanh lam) OR (hanh kem)) cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. hieu ((ve cam) or (ve cac)) tuc van ((hanh lam) OR (hanh kem)) cau tren*".
