Perhaps you should try some spelling variations:
cau tren » cu tren, dau tren, ca tren
cham xuc » cam xuc, chat xuc, cham soc
nang xa » nang x, lang xa, nang ma
va cham » va chat, va tham
cuu tre » cua tre, cau treo
va danh » va dinh, va hanh, dia danh
tu san » thu san, tu ban, tu can
va dan » ca dan, va dao, va dau
san ky » sang ky, van ky, dan ky

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

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