Perhaps you should try some spelling variations:
thanh hai » thanh phan, thanh hoa, thanh san
thuat san » thuat toan, thuat song, thuat lanh
hanh hai » nhanh hai, hang hai, hanh tai
hieu va » lieu va, hieu qua
cau tuc » cau truc, cau tu, cau luc
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
san ky » sang ky, van ky, dan ky
va cau » van cau, va cac, va dau

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat san ky nang x ho. hieu va cau tuc xa ((hanh hai) OR (thanh hai)) ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ky nang x ho. hieu va cau tuc xa ((hanh hai) OR (thanh hai)) ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ky nang x ho. hieu va cau tuc xa ((hanh hai) OR (thanh hai)) ((cua tre) or (cuu tre))*".
