Perhaps you should try some spelling variations:
phung cong » nhung cong, phong cong, nhung chong
hoc thieu » toc thieu
thong cua » thong quan, thong tu, huong cua
thang va » hang va, trang va, thong va
cong tan » cong tac, cong san, cong thanh
tan phan » toan phan, than phan, van phan
phan cac » nhan cach, phan dau, phan lap

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 thieu) OR (hoc hien)) xanh - nhanh ((thang va) OR (thong cua)) phung cong tan phan cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (hoc hien)) xanh - nhanh ((thang va) or (thong cua)) phung cong tan phan cac~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (hoc hien)) xanh - nhanh ((thang va) or (thong cua)) phung cong tan phan cac*.
