Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
tu sach » thu sach, su sach, te sach
vai cua » dai cua, hai cua, lai cua
xa hanh » xa thanh, xa khanh, va hanh
cua tre » cua te, cuu tre, cua triet
sang ma » tang ma, nang ma, sang tao
dam tu » nam tu, tam tu, dam thuc
cam tu » cam thu, nam tu, tam tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y ((nang x) or (sang ma)) hoi. lieu va ((cam tu) OR (dam tu)) xa hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang x) OR (sang ma)) hoi. lieu va ((cam tu) OR (dam tu)) xa hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((nang x) or (sang ma)) hoi. lieu va ((cam tu) OR (dam tu)) xa hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach y ((nang x) or (sang ma)) hoi. lieu va ((cam tu) OR (dam tu)) xa hanh vai cua tre*.
