Perhaps you should try some spelling variations:
thuat hanh » thuat thanh, thuat hinh, thuat canh
thuat lanh » thuat lap, thuat san
hanh ve » hanh vi, hanh va, hanh kem
va hanh » van hanh, va thanh, va danh
du tren » dua tren, dau tren, duc tren
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc va
va cau » van cau, va dau, va cao
ve du » ve su, te du, va du

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((thuat hanh) OR (thuat lanh)) y nang xa hoi. lieu ((va cau) or (va cac)) luc va hanh ve du tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat hanh) OR (thuat lanh)) y nang xa hoi. lieu ((va cau) OR (va cac)) luc va hanh ve du tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat hanh) OR (thuat lanh)) y nang xa hoi. lieu ((va cau) or (va cac)) luc va hanh ve du tren".
• Adding a wildcard symbol may retrieve word variants: ((thuat hanh) OR (thuat lanh)) y nang xa hoi. lieu ((va cau) or (va cac)) luc va hanh ve du tren*.
