Expressing "both… and…" with "ji...you"

A simple way to express that something is "both A and B" is to the following structure:

既 + adjective + 也 + adjective

The structure can also be formed with 又:

既 + adjective + 又 + adjective

These function in exactly the same way. Any two adjectives can be inserted into this structure. Some examples:

• 他 做 事情 既 快 又 好。
• 这 家 银行 的 服务既 热情 又周到。
• 这个 产品 的 设计 既 时尚 又 人性化。
