The original poster was misled! ! Don't take it for granted when answering questions. If you know something, you know it. If you don't know it, you don't know it.
Su: Always, Chang: Normal. "Keep Su An Chang" means don't rush to change your identity, just keep your existing identity. For example, if a husband feels that his wife is not good enough, if he is a "conservative" person, he will not be in a hurry to divorce her, but will work harder, accept her, help her become better, and find ways to Make two people more harmonious together. The source of this word is Chapter 7 of 1 Corinthians in the New Testament. Friends who are interested can read this chapter.
