Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
va cham » va chat, va tham
duc van » duc va, duc tan, duc manh
nang xa » nang x, lang xa, nang ma
vi cua » vai cua, di cua
va cam » va cac, va cao, va cai
cua te » cua tu
san y » san _
dan y » dan ky, dan _, day y

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((san y) OR (dan y)) nang xa hoi. lieu ((va cam) or (va cham)) duc van hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((san y) OR (dan y)) nang xa hoi. lieu ((va cam) OR (va cham)) duc van hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((san y) OR (dan y)) nang xa hoi. lieu ((va cam) or (va cham)) duc van hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: thuat ((san y) OR (dan y)) nang xa hoi. lieu ((va cam) or (va cham)) duc van hanh vi cua te*.
