The Chinese word 加强 (jiāqiáng) is composed of two characters: 加 (jiā) and 强 (qiáng). The character 加 originally meant "to add" or "to increase", and it is still used in this sense today. The character 强 originally meant "strong" or "powerful", and it is also still used in this sense today. When these two characters are combined, they create the word 加强, which means "to strengthen" or "to reinforce". This word can be used in a variety of contexts, such as to strengthen a relationship, to strengthen a building, or to strengthen one's immune system.
