Perhaps you should try some spelling variations:
tien thanh » tien thinh, den thanh
tran thanh » ban thanh, van thanh, quan thanh
canh manh » lanh manh, canh tranh, cach mang
nhan tong » nhan trong, nhan thong, nhan tuong
manh cua » doanh cua, ban cua
cua nhan » ca nhan, cua ngan, cua nha
tong dan » tuong dan, thong dan, trong dan
phan lap » phan dau
hang dau » hang va, hang tai

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: hoc ((tien thanh) OR (tran thanh)) - canh manh cua nhan tong dan ((phan lap) OR (hang dau))~.
• Adding a wildcard symbol may retrieve word variants: hoc ((tien thanh) or (tran thanh)) - canh manh cua nhan tong dan ((phan lap) or (hang dau))*.
