Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
thu san » thuy san, thu ban, phu san
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
cuu tre » cua tre, cau tren, cau treo
san ky » sang ky, van ky, dan ky
vi cuu » vi luu, vinh cuu
x hoi » xa hoi, x ho, 5 hoi
o hoi » co hoi, o hoc, o hai

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

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