Perhaps you should try some spelling variations:
thanh tinh » thanh binh, nhanh tinh, than kinh
va thanh » gia thanh, ban thanh, va tinh
tinh cuu » trinh cuu, dinh cuu, tinh cua
ve cham » va cham, ve chat, ve chim
vu cham » va cham, vu kham, tu cham
cuu tre » cua tre, cau tren, cau treo
loc va » hoc va, luc va
o lai » o lao

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky nang ((o lai) or (x ho)). hieu ((ve cham) OR (vu cham)) loc va thanh tinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang ((o lai) OR (x ho)). hieu ((ve cham) OR (vu cham)) loc va thanh tinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang ((o lai) or (x ho)). hieu ((ve cham) OR (vu cham)) loc va thanh tinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang ((o lai) or (x ho)). hieu ((ve cham) OR (vu cham)) loc va thanh tinh cuu tre*.
