Perhaps you should try some spelling variations:
xa thanh » va thanh, ha thanh, gia thanh
ta thanh » tai thanh, va thanh, ha thanh
tu sach » thu sach, su sach, te sach
cua tre » cua te, cua triet, dua tren
lam tuc » lam thuoc, lam truoc, luat tuc
hieu va » lieu va, hieu qua
cuu tre » cau tren, cau treo
y nang » ky nang, ly nang, v nang
va lam » van lam, va lap
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang x hoi. hieu va lam tuc ((xa thanh) or (ta thanh)) tinh ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x hoi. hieu va lam tuc ((xa thanh) OR (ta thanh)) tinh ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. hieu va lam tuc ((xa thanh) or (ta thanh)) tinh ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. hieu va lam tuc ((xa thanh) or (ta thanh)) tinh ((cua tre) OR (cuu tre))*.
