"Anti-counterfeiting" is one of the characteristics of signature. This kind of signature must follow the design rules, and can't ignore the statutes, wrap it at will, be too complicated or simplify the strokes. Anti-counterfeiting label, financial anti-counterfeiting label, etc. All fall into this category.

"The system of Si 'an originated in Han and Jin Dynasties, prevailed in Tang and Song Dynasties, was published in Yuan and Ming Dynasties, and declined in Qing Dynasty". "Signature design" has gone through a long road of ups and downs. Fortunately, today's people carry forward and form a rich signature culture!
