Perhaps you should try some spelling variations:
thuat sac » thuat sach, thuat san, thuat tac
dan thai » dang thai, dan than, ban thai
dan thi » dang thi, tran thi, dinh thi
van hoc » van hoa
van hac » van ha, van hai, van chat
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: thuat sac ky nang x hoi. thien ((van hac) OR (van hoc)) xuc va ((dan thai) or (dan thi)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sac ky nang x hoi. thien ((van hac) OR (van hoc)) xuc va ((dan thai) OR (dan thi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sac ky nang x hoi. thien ((van hac) OR (van hoc)) xuc va ((dan thai) or (dan thi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: thuat sac ky nang x hoi. thien ((van hac) OR (van hoc)) xuc va ((dan thai) or (dan thi)) cua tre*.
