Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
han thai » han tai, ban thai, van thai
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
va cham » va chat, va tham
thai va » thai van
sac ky » sai ky
xuc va » duc va, tuc va, luc va
va han » va phan, van han, va hanh
thiet » thieu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sac ky) OR (cac ky)) ((nang xa) OR (lang xa)) hoi. hieu va cham xuc va han thai va thiet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sac ky) OR (cac ky)) ((nang xa) or (lang xa)) hoi. hieu va cham xuc va han thai va thiet~".
• Adding a wildcard symbol may retrieve word variants: thuat ((sac ky) OR (cac ky)) ((nang xa) or (lang xa)) hoi. hieu va cham xuc va han thai va thiet*.
