Perhaps you should try some spelling variations:
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
va cham » va chat, va tham
han tai » hang tai, nhan tai, van tai
xuc va » tuc va, luc va, xac va
tai va » thai va, mai va, tri va
thiet » thieu

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. lieu va cham ((((xuc va) or (tuc xa))) or (duc va)) han tai va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. lieu va cham ((((xuc va) OR (tuc xa))) OR (duc va)) han tai va thiet.
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. lieu va cham ((((xuc va) or (tuc xa))) or (duc va)) han tai va thiet*.
