Perhaps you should try some spelling variations:
ky tang » ky dang, kho tang, ky trong
ve cham » ve chat, vu cham, ve chim
va cham » va chat, va tham
han tri » han tai, van tri, thanh tri
su xac » pu xac, su cac
xuc va » duc va, tuc va, luc va
va han » va phan, van han, va hanh
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: su xac ((ky tang) OR (ky nang)) xa hoi. hieu ((ve cham) or (va cham)) xuc va han tri va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ((ky tang) OR (ky nang)) xa hoi. hieu ((ve cham) OR (va cham)) xuc va han tri va thiet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ((ky tang) OR (ky nang)) xa hoi. hieu ((ve cham) or (va cham)) xuc va han tri va thiet".
• Adding a wildcard symbol may retrieve word variants: su xac ((ky tang) OR (ky nang)) xa hoi. hieu ((ve cham) or (va cham)) xuc va han tri va thiet*.
