Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
hanh li » nhanh li, hanh vi, thanh loi
ca viet » va viet, co viet, hoa viet
sac ky » sai ky
ve cam » ve cham, ve cac, va cam
han li » shan li, ban li, dan li

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sac ky) or (cac ky)) nang xa hoi. hieu ve cam duc va ((hanh li) OR (han li)) ca viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (cac ky)) nang xa hoi. hieu ve cam duc va ((hanh li) OR (han li)) ca viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) or (cac ky)) nang xa hoi. hieu ve cam duc va ((hanh li) OR (han li)) ca viet".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) or (cac ky)) nang xa hoi. hieu ve cam duc va ((hanh li) OR (han li)) ca viet*.
