Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, le thanh
nang cau » nang cao, hang cau, nang dau
luy tre » luyen tre
luu tre » luu tru, cuu tre
va tinh » may tinh
hieu ve » hieu va, hieu van
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
te sac » te sach, te cac, te san

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang cau hoi. hieu ve cam xuc ((va thanh) OR (va tinh)) vi ((luu tre) or (luy tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang cau hoi. hieu ve cam xuc ((va thanh) OR (va tinh)) vi ((luu tre) OR (luy tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang cau hoi. hieu ve cam xuc ((va thanh) OR (va tinh)) vi ((luu tre) or (luy tre))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang cau hoi. hieu ve cam xuc ((va thanh) OR (va tinh)) vi ((luu tre) or (luy tre))*.
