Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
cay phoi » cap phoi, tay hoi, cay cho
ky dang » ky nang, ky danh
hieu ve » hieu va, hieu van
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
ve cac » va cac, vien cac
cua te » cua tu

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 dang ((cay phoi) or (xa hoi)). hieu ve cac ((xuc van) OR (duc van)) thanh dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky dang ((cay phoi) OR (xa hoi)). hieu ve cac ((xuc van) OR (duc van)) thanh dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky dang ((cay phoi) or (xa hoi)). hieu ve cac ((xuc van) OR (duc van)) thanh dai cua te".
• Adding a wildcard symbol may retrieve word variants: tu cac ky dang ((cay phoi) or (xa hoi)). hieu ve cac ((xuc van) OR (duc van)) thanh dai cua te*.
