Perhaps you should try some spelling variations:
thanh trung » thanh tung
thieu hach » thien hach, chieu sach, hieu cach
trung tuan » trung thanh, trung tam, tran tuan
thong cong » trong cong, thong thong, phong chong
hoc thieu » toc thieu, hoc hien
tong cong » trong cong, cong cong, dung cong
doan tuan » doan quan, doanh luan, doan quang
tuan cau » toan cau, quan cau, tuan cu

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 hach - thanh trung tuan ((thong cong) OR (tong cong)) doan tuan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu hach - thanh trung tuan ((thong cong) OR (tong cong)) doan tuan cau*.
