Perhaps you should try some spelling variations:
chan thuong » phan thuong, han thuong, hang thuong
thuong cong » thong cong, thuong con, thuong dong
hanh trung » thanh trung, hanh trang, manh trung
trung chan » trung phan, trong chan, trung can
khi xanh » khia canh, thi hanh, thi anh
cong tan » cong tac, cong san, cong thanh
toan ban » van ban

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: "doi khi xanh - hanh trung chan thuong cong tan ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - hanh trung chan thuong cong tan ((toan tap) OR (toan ban))*.
