Perhaps you should try some spelling variations:
thanh dat » thanh san, thanh hai, thanh van
hanh dao » thanh dam, doanh dao, hanh duoc
cua tre » cua te, cuu tre, cua triet
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
xuc va » duc va, tuc va, luc va
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
tu sac » tu sach, tu cac, tu san

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 lang xa hoi. hieu va cam xuc va ((((hanh dao) OR (thanh dat))) or (lanh dao)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. hieu va cam xuc va ((((hanh dao) OR (thanh dat))) OR (lanh dao)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu va cam xuc va ((((hanh dao) OR (thanh dat))) or (lanh dao)) cua tre*".
