Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
cuu tre » cua tre, cau tren, cau treo
tai cuu » tai cuc, tai buu, tai cua
va hanh » van hanh, va thanh, va danh
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
luc va » duc va, tuc va, loc va
te sac » te sach, te cac
te san » te ban, ke san, tu san
va cam » va cham, va cac, va cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((te sac) OR (te san)) ky dang xa hoi. hieu ((va cam) or (va phat)) luc va hanh tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te san)) ky dang xa hoi. hieu ((va cam) OR (va phat)) luc va hanh tai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te san)) ky dang xa hoi. hieu ((va cam) or (va phat)) luc va hanh tai cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((te sac) OR (te san)) ky dang xa hoi. hieu ((va cam) or (va phat)) luc va hanh tai cuu tre*.
