Jiema, also known as cryptography, is an ancient art that involves the creation and deciphering of secret codes and messages. Dating back to ancient civilizations, this practice has been vital in protecting confidential information throughout history. The Chinese word “jiema” literally translates to “decode”, reflecting the essence of this intriguing practice. In ancient times, various methods such as substitution ciphers, transposition ciphers, and even invisible inks were used to conceal messages. Today, cryptography has evolved into complex algorithms and mathematical computations, ensuring secure communication, online transactions, and data protection. Jiema serves as a reminder of the importance of confidentiality and the fascinating ways in which humanity has sought to keep secrets hidden.#32#
