Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
trinh quan » tinh quang, trinh luat
hoc thieu » toc thieu, hoc hien
han trong » hanh trong, nhan trong, phan trong
trong van » trong cac
van tan » van tuan, van ban, van tai
tan ban » toan ban, tang ban, van ban

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: hoc thieu xanh - hanh ((trinh quan) OR (trinh han)) han trong van tan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((trinh quan) or (trinh han)) han trong van tan ban*.
