Perhaps you should try some spelling variations:
thanh tung » thanh cong
tung tuan » trung tuan, hung tuan, quang tuan
tuan hang » tuan hoang, tuan bang, tuan dang
hang cong » dang cong, hang nong, bang cong
hoc dieu » hoc thieu
cong tan » cong tac, cong san, cong thanh
phan lap » phan dau

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 dieu) OR (hoc hien)) hanh - thanh tung tuan hang cong tan ((phan lap) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc dieu) OR (hoc hien)) hanh - thanh tung tuan hang cong tan ((phan lap) or (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc dieu) OR (hoc hien)) hanh - thanh tung tuan hang cong tan ((phan lap) or (phan tu))*.
