Perhaps you should try some spelling variations:
thanh lap » thanh san, phan lap, thanh hai
cham xuc » cam xuc, chat xuc, cham soc
dua tren » dung tren
va thanh » gia thanh, ban thanh, va tinh
va cham » va chat, va tham
tu sach » thu sach, su sach, te sach
hieu va » lieu va, hieu qua
cuu tre » cua tre, cau tren, cau treo
y lang » _ lang, tay lang, yen lang
xuc va » duc va, tuc va, luc va
o lang » hoa lang, hoi lang

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 lang) OR (o lang)) xa hoi. hieu va cham xuc va thanh lap ((dua tren) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y lang) OR (o lang)) xa hoi. hieu va cham xuc va thanh lap ((dua tren) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y lang) OR (o lang)) xa hoi. hieu va cham xuc va thanh lap ((dua tren) or (cuu tre))*".
