Perhaps you should try some spelling variations:
chat xuc » chat huu, cam xuc, chao xu
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
va chat » van chat, va phat, cao chat
hieu va » lieu va, hieu qua
te sach » toc sach
tu nang » tru nang, tu nong, tu lang
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va
di cua » dai cua, doi cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((((tu nang) OR (tu nano))) or (truc nano)) xa hoi. hieu va chat xuc va hanh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((((tu nang) OR (tu nano))) OR (truc nano)) xa hoi. hieu va chat xuc va hanh di cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((((tu nang) OR (tu nano))) or (truc nano)) xa hoi. hieu va chat xuc va hanh di cua tre*".
