Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
ve cham » va cham, ve chat, vu cham
kien ca » kien ha, kien va, bien ca
va dinh » van dinh, va kinh, va tinh
va danh » va dan, va hanh, dia danh
ca tren » cau tren, cu tren, la tren
nang xa » lang xa, nang ma, mang xa
hieu ve » hieu va, hieu van
dan ky » van ky
tu dan » tuc dan, tu ban, cu dan

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu dan ky ((nang xa) or (nang x)) hoi. hieu ve cham xuc ((va danh) OR (va dinh)) kien ca tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ky ((nang xa) OR (nang x)) hoi. hieu ve cham xuc ((va danh) OR (va dinh)) kien ca tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ky ((nang xa) or (nang x)) hoi. hieu ve cham xuc ((va danh) OR (va dinh)) kien ca tren".
• Adding a wildcard symbol may retrieve word variants: tu dan ky ((nang xa) or (nang x)) hoi. hieu ve cham xuc ((va danh) OR (va dinh)) kien ca tren*.
