Perhaps you should try some spelling variations:
trinh quan » tinh quang, trinh luat, trinh han
trinh cua » tinh cua, trinh luat, trinh luan
thien van » thi van
toc sac » toc sach, toc san, hoc sach
va hanh » van hanh, va thanh, va danh
van cam » van nam, van lam, van cau
cam luc » cam xuc, cau luc
luc va » duc va, tuc va, loc va
o lang » hoa lang, hoi lang
ha hoi » hoa hoi, xa hoi, va hoi

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

• Performing a fuzzy search may retrieve terms with similar spellings: toc sac o lang ((ha hoi) OR (ha noi)). thien van cam luc va hanh ((trinh cua) or (trinh quan)) tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac o lang ((ha hoi) OR (ha noi)). thien van cam luc va hanh ((trinh cua) OR (trinh quan)) tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac o lang ((ha hoi) OR (ha noi)). thien van cam luc va hanh ((trinh cua) or (trinh quan)) tu*".
