Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thanh tai » thanh hai, thanh toan, doanh tai
thu sach » tu sach, thuat sach, thuoc sach
cham xuc » cam xuc, chat xuc, chao xu
nang ma » tang ma, sang ma, nang cao
hieu ve » hieu va, hieu van
cuc tre » duc tre, cua tre, cuu tre
y nang » ky nang, ly nang, v nang

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sach y nang ma hoa. hieu ve ((((cham xuc) OR (pham duc))) or (cham soc)) ban thanh tai cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang ma hoa. hieu ve ((((cham xuc) OR (pham duc))) OR (cham soc)) ban thanh tai cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang ma hoa. hieu ve ((((cham xuc) OR (pham duc))) or (cham soc)) ban thanh tai cuc tre".
• Adding a wildcard symbol may retrieve word variants: thu sach y nang ma hoa. hieu ve ((((cham xuc) OR (pham duc))) or (cham soc)) ban thanh tai cuc tre*.
