Perhaps you should try some spelling variations:
mang mai » mang may, lang mai, mang lai
hanh tai » thanh tai, hang tai, hinh tai
dam thuc » am thuc, dan thuc, nam thuc
te sach » toc sach
han tai » hang tai, nhan tai, van tai
cuu tre » cua tre, cau tren, cau treo
mai hoi » mai khoi, dai hoi, lai hoi
hieu ve » hieu va, hieu van
dam tu » nam tu, cam tu, tam tu
y mang » cay mang

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y mang mai hoi. hieu ve ((dam thuc) or (dam tu)) va ((hanh tai) OR (han tai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y mang mai hoi. hieu ve ((dam thuc) OR (dam tu)) va ((hanh tai) OR (han tai)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y mang mai hoi. hieu ve ((dam thuc) or (dam tu)) va ((hanh tai) OR (han tai)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach y mang mai hoi. hieu ve ((dam thuc) or (dam tu)) va ((hanh tai) OR (han tai)) cuu tre*.
