English-Chinese refers to the relationship between the English language and the Chinese language, which are two of the most widely spoken languages in the world. English is a Germanic language primarily spoken in countries like the United States and United Kingdom, while Chinese, particularly Mandarin, is a Sino-Tibetan language spoken mainly in China and among Chinese communities worldwide. The two languages differ significantly in grammar, vocabulary, and writing systems. English uses the Latin alphabet, while Chinese employs characters known as Hanzi. Learning either language can provide valuable opportunities for communication, business, and cultural exchange between Western and Eastern societies.
