Perhaps you should try some spelling variations:
trong thanh » truong thanh, trung thanh, rong thanh
theo chieu » theo tieu, ho chieu, theo chu
chieu sang » chieu sach, chieu xanh, hieu lang
truong cao » truong dai
thanh toan » thanh hoa, thanh san, tinh toan
truong ca » truong va, trong ca, truong dai
tran tuan » tran xuan, tran quang, tran thanh
toan tap » toan ban

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 chieu sang - thanh ((((truong ca) OR (truong cao))) OR (tran tuan)) dung trong thanh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sang - thanh ((((truong ca) OR (truong cao))) or (tran tuan)) dung trong thanh toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - thanh ((((truong ca) OR (truong cao))) or (tran tuan)) dung trong thanh toan tap*.
