nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua

sac van » san van, sat van, tac van
cac van » cac 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 van ky nang xa hoi. hieu va cham ((soc van) or (((sac van) OR (cac van)))) hanh dao cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky nang xa hoi. hieu va cham ((soc van) OR (((sac van) OR (cac van)))) hanh dao cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky nang xa hoi. hieu va cham ((soc van) or (((sac van) OR (cac van)))) hanh dao cua triet".
• Adding a wildcard symbol may retrieve word variants: tu van ky nang xa hoi. hieu va cham ((soc van) or (((sac van) OR (cac van)))) hanh dao cua triet*.
