Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
trung tuan » trung thanh, trung tam, truong thanh
thong cong » trong cong, tong cong, thong thong
hoc thieu » toc thieu, hoc hien
tran tuan » tran xuan, tran quang, tran thanh
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan cao » toan ban, toan tap

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu manh - manh ((trung tuan) OR (tran tuan)) thong cong van toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu manh - manh ((trung tuan) OR (tran tuan)) thong cong van toan cao*.
