Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
ve cham » va cham, ve chat, vu cham
va hanh » van hanh, va thanh, va danh
lang xa » lang ha, dang xay, lang van
vi cua » vai cua, di cua
loc va » hoc va, luc va
sac ky » sai ky
ve cam » ve cac, va cam, ve cai

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sac ky) or (cac ky)) lang xa hoi. hieu ((ve cam) OR (ve cham)) loc va hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (cac ky)) lang xa hoi. hieu ((ve cam) OR (ve cham)) loc va hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) or (cac ky)) lang xa hoi. hieu ((ve cam) OR (ve cham)) loc va hanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) or (cac ky)) lang xa hoi. hieu ((ve cam) OR (ve cham)) loc va hanh vi cua tre*.
