Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
cong ngang » cong nhan, cong quang, cong lang
ngang tuan » quang tuan, hoang tuan, nganh toan
doi chieu » doc hieu, doi chi, ho chieu
truong va » truong dai, truong cao, truong dao
tong cong » trong cong, cong cong, dung cong
tuan chau » tran chau, chuan chau, thanh chau
trung va » trang va, trung tam, trung cap
trung ha » trung hoc, trung tam, trung cap

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: doi chieu xanh - thanh ((((trung va) OR (truong va))) OR (trung ha)) tong cong ngang tuan chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - thanh ((((trung va) OR (truong va))) or (trung ha)) tong cong ngang tuan chau~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - thanh ((((trung va) OR (truong va))) or (trung ha)) tong cong ngang tuan chau*.
