Perhaps you should try some spelling variations:
thieu tinh » trieu tinh, chieu tinh, thien tinh
nhu phuong » thu phuong, nhung phuong, thi phuong
phuong tan » phuong tran, phuong tay, phuong lan
hoc thieu » toc thieu, hoc hien
tranh cua » doanh cua, manh cua
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
tan van » tran van, tang van, luan van

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 tinh - hanh ((tranh cua) OR (((trung cua) OR (trung cap)))) nhu phuong tan van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - hanh ((tranh cua) or (((trung cua) OR (trung cap)))) nhu phuong tan van ban~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - hanh ((tranh cua) or (((trung cua) OR (trung cap)))) nhu phuong tan van ban*.
