Perhaps you should try some spelling variations:
thanh tung » thanh cong
tung tuan » trung tuan, hung tuan, quang tuan
tuan dung » tuan duong, tran dung, tan dung
dung cong » dung trong
cong toan » cong tan, cong hoan, cong tuan
khan cap » than cap, khoan cam, phan cac
ho kieu » ho lieu, so kieu, thi kieu
so lieu » so dieu
khan ap » han ap, khan dam

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: ((ho kieu) OR (so lieu)) tinh - thanh tung tuan dung cong toan ((khan cap) OR (khan ap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho kieu) or (so lieu)) tinh - thanh tung tuan dung cong toan ((khan cap) OR (khan ap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho kieu) or (so lieu)) tinh - thanh tung tuan dung cong toan ((khan cap) OR (khan ap))*.
