In this topic, Party B thinks that the signature behavior belongs to sign-in, and there is no expression of intention to have business relationship or other legal relationship with Party A at all, which does not constitute expression of intention.

However, in some behavior made by coercion, although the actor was coerced, he still made a declaration of will, but the declaration of will was not the true expression of his heart. Therefore, the act is also an ideographic act, just because the law guarantees the autonomy of the parties and stipulates that the ideographic act made by coercion is a revocable ideographic act (that is, one of the illegal civil acts).
