Perhaps you should try some spelling variations:
thanh dat » thanh san, thanh hai, thanh van
de triet » ve triet, de thiet, su triet
xa thanh » va thanh, ha thanh, ta thanh
va cham » va chat, va tham
tu sach » thu sach, su sach, te sach
ky dang » ky danh
ve chat » va chat, van chat
ha hoi » hoa hoi, ha noi, xa hoi
dat de » vat de, dat ve, hat de

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