Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
cau tren » cu tren, dau tren, ca tren
thanh de » hanh de, thanh ve, thanh do
cham xuc » chat xuc, cham soc, pham duc
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
da nang » cam nang, kha nang, cao nang
ha nang » kha nang, hoa nang, ha tang
de cau » ke cau, le cau, ve cau

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 ((ha nang) OR (da nang)) xa hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh de cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ha nang) OR (da nang)) xa hoi. hieu ve ((cham xuc) OR (cam xuc)) ban thanh de cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ha nang) OR (da nang)) xa hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh de cau tren".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ha nang) OR (da nang)) xa hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh de cau tren*.
