Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh tai, thanh oai
thanh van » thanh san, thanh toan, thanh phan
vien dai » hien dai
cua tre » cua te, cuu tre, cua triet
xuc van » duc van, luc van, vuc van
nang ma » tang ma, sang ma, nang cao
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
su sac » su sach, su cac, su xac

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 nang ma hoa. hieu ((ve cac) or (vien dai)) xuc van ((thanh vai) OR (thanh van)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang ma hoa. hieu ((ve cac) OR (vien dai)) xuc van ((thanh vai) OR (thanh van)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang ma hoa. hieu ((ve cac) or (vien dai)) xuc van ((thanh vai) OR (thanh van)) cua tre*".
