Perhaps you should try some spelling variations:
thanh tung » thanh cong
hua khong » hoa khong, hoac khong, phuc khong
cua khong » cua phuong, cua thuong, cua cong
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
canh dan » canh van, sanh dan, thanh dan
dan chan » dan gian, dan ca, van chat
chan cau » phan cau, can cau, chinh cau

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: theo chu xanh - ((thanh trung) OR (thanh tung)) ((hua khong) OR (cua khong)) canh dan chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((thanh trung) OR (thanh tung)) ((hua khong) or (cua khong)) canh dan chan cau~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((thanh trung) OR (thanh tung)) ((hua khong) or (cua khong)) canh dan chan cau*.
