Lei came in at number two. This term began as the Chinese noun for "thunder" and has recently been repurposed as a verb and adjective indicating shock or alarm-for example, something can be described as hen lei, meaning it is "very shocking / startling," and a person may say they have bei leidao, literally "been thundered," meaning they have been shocked or startled.
「雷」排名第二，這個字原來是名詞，現在被當成動詞或形容詞，表示非常震驚或驚嚇。如：「很雷」、「被雷到」等。
