Perhaps you should try some spelling variations:
thieu lang » hieu lang, thieu khang, thieu quang
thanh tung » thanh cong
hoc thieu » toc thieu, hoc hien
trong cau » trong cac, trong ca, thong cau
phan cau » phan dau, phan tu, phan lap
phan cac » nhan cach, phan dau, phan lap
va dung » van dung, va duong, vat dung

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc thieu lang - ((thanh trung) OR (thanh tung)) va dung trong cau ((phan cau) or (phan cac))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu lang - ((thanh trung) OR (thanh tung)) va dung trong cau ((phan cau) OR (phan cac)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu lang - ((thanh trung) OR (thanh tung)) va dung trong cau ((phan cau) or (phan cac))".
• Adding a wildcard symbol may retrieve word variants: hoc thieu lang - ((thanh trung) OR (thanh tung)) va dung trong cau ((phan cau) or (phan cac))*.
