通信

通信 refers to the act of exchanging information between individuals or systems. It is a broad term that can encompass both traditional methods like letters and modern ones like digital messaging.

The character 通 (tōng) means 'to pass through' or 'to be connected,' while 信 (xìn) means 'letter' or 'message.' Together, they form a term that emphasizes the connection and exchange of information.

Communication is essential in both personal and professional contexts. In China, it is widely used in technology, business, and daily life, especially with the rise of mobile internet and social media platforms.
