Perhaps you should try some spelling variations:

ban thanh » ban hanh, ban hang
cham xuc » cam xuc, chat xuc, cham soc
va thanh » gia thanh, va tinh, le thanh
dai cuu » dai cua, dai huu
va cham » va chat, va tham
hieu va » lieu va, hieu qua
lang ha » long ha
lang xa » dang xay, lang van
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: thuat sach y ((lang xa) or (lang ha)) hoi. hieu va cham xuc ((va thanh) OR (ban thanh)) dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach y ((lang xa) OR (lang ha)) hoi. hieu va cham xuc ((va thanh) OR (ban thanh)) dai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach y ((lang xa) or (lang ha)) hoi. hieu va cham xuc ((va thanh) OR (ban thanh)) dai cuu tre".
• Adding a wildcard symbol may retrieve word variants: thuat sach y ((lang xa) or (lang ha)) hoi. hieu va cham xuc ((va thanh) OR (ban thanh)) dai cuu tre*.
