Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
trung cua » truong cua, trung tuan, trung cap
cong tinh » cong trinh, cong vinh, long tinh
van cong » van dong, van phong, phan cong
toan ban » van ban
cua van » cua ban, cua vat, cua dan

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: "ho ((chieu xanh) OR (chieu sang)) - thanh trung cua van cong tinh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - thanh trung cua van cong tinh toan ban*.
