Perhaps you should try some spelling variations:
nhanh hai » nhanh thai, thanh hai, nhanh ha
hanh hai » thanh hai, hang hai, hanh tai
chi tre » choi tre, cho tre, chi tro
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cam duc » cam xuc, cao duc, pham duc
sai ky » sac ky
va cam » va cham, va cac, va cao

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

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