Perhaps you should try some spelling variations:
nhanh hai » nhanh thai, thanh hai, nhanh ha
hanh hai » thanh hai, hang hai, hanh tai
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam

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

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