Perhaps you should try some spelling variations:
thanh toan » thanh hoa, thanh san, tinh toan
thanh phan » thanh pho, thanh san, thanh hai
cua tre » cua te, cuu tre, cua triet
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
xuc ban » duc ban, cuc ban, quoc ban
su sac » su sach, su cac, su xac
va cam » va cham, va cac, va cao
sac ky » cac ky, sai ky
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 ky dang xa hoi. hieu ((ve cam) or (va cam)) xuc ban ((thanh phan) OR (thanh toan)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky dang xa hoi. hieu ((ve cam) OR (va cam)) xuc ban ((thanh phan) OR (thanh toan)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky dang xa hoi. hieu ((ve cam) or (va cam)) xuc ban ((thanh phan) OR (thanh toan)) cua tre*".
