Perhaps you should try some spelling variations:
lieu van » lieu va, hieu van, sieu van
van tham » van thanh, van tuan, van chat
thuc dan » hoc dan, thuc vat
danh dai » danh dau, danh di, danh sai
sach ky » sach y, sach ty, sach kem
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky, sai ky
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: te ((sach ky) OR (sac ky)) nang x hoi. lieu van tham ((thuc dan) or (thuc hanh)) danh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) nang x hoi. lieu van tham ((thuc dan) OR (thuc hanh)) danh dai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) nang x hoi. lieu van tham ((thuc dan) or (thuc hanh)) danh dai cua tre*".
