Perhaps you should try some spelling variations:
thanh phan » thanh pho, thanh san, thanh toan
ban thanh » ban hanh, ban hang
phan cuu » phan cau, phan huu, phan cung
cuu tre » cua tre, cau tren, cau treo
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
duc ban » duc tan, duc van, dua ban
su sac » su cac, su xac
va cam » va cham, va cac, va cao
ve cam » ve cham, ve cac, ve cai

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) OR (su sach)) ky nang xa hoi. hieu ((ve cam) or (va cam)) duc ban thanh phan cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su sach)) ky nang xa hoi. hieu ((ve cam) OR (va cam)) duc ban thanh phan cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su sach)) ky nang xa hoi. hieu ((ve cam) or (va cam)) duc ban thanh phan cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su sach)) ky nang xa hoi. hieu ((ve cam) or (va cam)) duc ban thanh phan cuu tre*.
