Perhaps you should try some spelling variations:
cham xuc » cham soc, pham duc, chao xu
chat xuc » chat huu, chao xu, chat cua
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
han tai » hang tai, nhan tai, van tai
va han » va phan, van han, va hanh
tai va » thai va, mai va, tri va
thiet » thieu

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. hieu ve ((((cham xuc) OR (cam xuc))) or (chat xuc)) va han tai va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu ve ((((cham xuc) OR (cam xuc))) OR (chat xuc)) va han tai va thiet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. hieu ve ((((cham xuc) OR (cam xuc))) or (chat xuc)) va han tai va thiet".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. hieu ve ((((cham xuc) OR (cam xuc))) or (chat xuc)) va han tai va thiet*.
