Perhaps you should try some spelling variations:
trinh han » trinh quan
dang cong » dung cong
chi xanh » chi anh, chi danh, chi hanh
tinh cua » trinh cua, sinh cua, tinh chat
cong anh » cong danh, dong anh, hong anh
tuan tap » tuan tai, tuyen tap, toan tai
toan tap » toan ban
doi chi » doi khi

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 chi xanh - hanh ((trinh han) OR (tinh cua)) dang cong anh ((tuan tap) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi xanh - hanh ((trinh han) or (tinh cua)) dang cong anh ((tuan tap) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - hanh ((trinh han) or (tinh cua)) dang cong anh ((tuan tap) OR (toan tap))*.
