Perhaps you should try some spelling variations:
hanh hai » thanh hai, nhanh hai, hang hai
tan hanh » tan thanh, tang hanh, toan hanh
cua tre » cua te, cuu tre, cua triet
nang xa » lang xa, nang ma, mang xa
hai cua » thai cua, dai cua, hoi cua
ve cac » va cac, vien cac
su sai » su tai, su hai, su dai
sai ky » sac ky
ve cam » ve cham, 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: su sai ky ((nang xa) OR (nang x)) hoi. hieu ((ve cam) or (ve cac)) duc tan hanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky ((nang xa) OR (nang x)) hoi. hieu ((ve cam) OR (ve cac)) duc tan hanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky ((nang xa) OR (nang x)) hoi. hieu ((ve cam) or (ve cac)) duc tan hanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: su sai ky ((nang xa) OR (nang x)) hoi. hieu ((ve cam) or (ve cac)) duc tan hanh hai cua tre*.
