Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
thanh te » thanh ve, thanh de, thanh le
trung ha » trung hoc, trung tam, trung cap
thu sac » thu sach, thu san, thu xac
cua tre » cua te, cua triet, dua tren
xuc van » duc van, luc van, vuc van
cuu tre » cau tren, cau treo
hieu so » thieu so
tang ha » lang ha, tang ma, tang van
sac ky » cac ky, sai ky
so cam » so cap, so lam, bo cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky ((tang ha) OR (trung ha)) noi. hieu so cam xuc van thanh te ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky ((tang ha) OR (trung ha)) noi. hieu so cam xuc van thanh te ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky ((tang ha) OR (trung ha)) noi. hieu so cam xuc van thanh te ((cua tre) or (cuu tre))*".
