Perhaps you should try some spelling variations:
nam thuc » nam thuoc, am thuc, nam thu
hanh tai » thanh tai, han tai, hinh tai
hang tai » hang va, dung tai
nang xa » nang x, lang xa, nang ma
lieu ha » lieu nha, lieu va, liem ha
thuc xa » thuc xay, tuc xa, thuc va
cuu tre » cua tre, cau tren, cau treo

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cac) or (tu cach)) ky nang xa hoi. lieu ha nam thuc xa ((hanh tai) OR (hang tai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cac) OR (tu cach)) ky nang xa hoi. lieu ha nam thuc xa ((hanh tai) OR (hang tai)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cac) or (tu cach)) ky nang xa hoi. lieu ha nam thuc xa ((hanh tai) OR (hang tai)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu cac) or (tu cach)) ky nang xa hoi. lieu ha nam thuc xa ((hanh tai) OR (hang tai)) cuu tre*.
