Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
khong dang » khong cang, khong dung, khong dong
dang thanh » dong thanh, dang hanh, hoang thanh
chinh cua » chinh sua, hinh cua, chinh luan
ho chieu » theo chieu, hoc thieu, doi chieu
chinh ca » chinh ta, chinh va, chinh tai
sang ban » hang ban, nang ban, sang bae
san ban » van ban, can ban, san van

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 chieu xanh - hanh ((chinh cua) OR (chinh ca)) khong dang thanh ((san ban) OR (sang ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((chinh cua) or (chinh ca)) khong dang thanh ((san ban) OR (sang ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh ((chinh cua) or (chinh ca)) khong dang thanh ((san ban) OR (sang ban))*.
