Perhaps you should try some spelling variations:

van thanh » ban thanh, van tuan
cham luc » cham soc, cham cuu, chat lua
nhan luc » nang luc
sang cuu » song cuu, sang cua, mang cua
cuu tre » cua tre, cau tren, cau treo
hieu vu » hieu va, hieu ve, hieu su
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
tu san » thu san, tu ban, tu can

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) or (tu cac)) ky lang xa hoi. hieu vu ((cham luc) OR (nhan luc)) van thanh sang cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu san) OR (tu cac)) ky lang xa hoi. hieu vu ((cham luc) OR (nhan luc)) van thanh sang cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) or (tu cac)) ky lang xa hoi. hieu vu ((cham luc) OR (nhan luc)) van thanh sang cuu tre*".
