Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
thuong co » thuong con, thong co, thuong ho
ho chieu » theo chieu, hoc thieu, doi chieu
dinh cua » sinh cua, dinh cu, tinh cua
dinh cuu » dinh chi
co thanh » cho thanh, o thanh, co tranh
nhan tai » hang tai, van tai, toan tai
han tap » han tai, toan tap, nhan tao

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 sang - hanh ((dinh cua) OR (dinh cuu)) thuong co thanh ((han tap) OR (nhan tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - hanh ((dinh cua) or (dinh cuu)) thuong co thanh ((han tap) OR (nhan tai))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - hanh ((dinh cua) or (dinh cuu)) thuong co thanh ((han tap) OR (nhan tai))*.
