Perhaps you should try some spelling variations:
thieu tinh » trieu tinh, chieu tinh, thien tinh
hoc thieu » toc thieu, hoc hien
trinh cua » trinh luat, trinh quan, trinh luan
dung cong » dung trong
tinh cua » sinh cua, tinh chat, tranh cua
cong dan » cong san, cong tan, huong dan
phan cac » nhan cach, phan dau, phan lap

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 ((trinh cua) OR (tinh cua)) dung cong dan ((phan cac) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - hanh ((trinh cua) OR (tinh cua)) dung cong dan ((phan cac) or (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - hanh ((trinh cua) OR (tinh cua)) dung cong dan ((phan cac) or (phan tu))*.
