Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
hanh de » hanh ve, hanh kem
duc van » duc va, duc tan, duc manh
va cam » va cham, va cac, va cao
de cua » le cua, te cua, dieu cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve tai » te tai, de tai, le tai
ve cai » va cai, ve cac, ve cau

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ((((ve cai) OR (ve tai))) OR (va cam)) duc van hanh de cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ((((ve cai) OR (ve tai))) or (va cam)) duc van hanh de cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ((((ve cai) OR (ve tai))) or (va cam)) duc van hanh de cua tre*.
