Perhaps you should try some spelling variations:
sach thi » sach thu, sach tai, sach thieu
thi hanh » thi thanh
hanh cho » danh cho, hang cho, han cho
van hanh » van thanh, ban hanh, van anh
chat xuc » chat huu, cam xuc, chao xu
te sach » toc sach
cua cau » cua cac, cua chu, cua can
cua cay » cua cac
cac xuc » cam xuc, cac nuoc, cac cuoc
hieu ve » hieu va, hieu van
cho hoc » co hoc, khoa hoc

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 thi hanh cho hoc. hieu ve ((cac xuc) OR (chat xuc)) van hanh vi ((cua cau) or (cua cay))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thi hanh cho hoc. hieu ve ((cac xuc) OR (chat xuc)) van hanh vi ((cua cau) OR (cua cay))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thi hanh cho hoc. hieu ve ((cac xuc) OR (chat xuc)) van hanh vi ((cua cau) or (cua cay))*".
