The signature is usually Zhu and Bai. We should follow the principle of "Zhu first, then Bai". Generally, Zhu is the name seal, and white is the study seal. The position should be covered under the signature or at the lower left of the signature (slightly to the side). It's best not to print your name and nickname at the same time. If you want to stamp at the same time, the name is printed on it and the other number is printed on the bottom.
At present, the mainstream of calligraphy seal is in the lower right corner, whether in the upper left corner or the lower right corner.
