Good good study day day up的意思

"Good good study, day day up" is a phrase that is often used humorously or ironically, especially in online communities and social media. It is a playful English-language adaptation of a Chinese saying, "好好學習，天天向上," which is used to encourage constant learning and improvement.

The phrase gained popularity in English-speaking internet culture due to its amusing sound and the contrast between the seriousness of the sentiment and the playful way it is expressed. It is often used in a lighthearted manner to motivate oneself or others to study or to keep improving, often with a tongue-in-cheek attitude.

Here's a breakdown of the phrase:

• "Good good" is an English repetition for emphasis, similar to saying "very good" or "really good."
• "Study" refers to the act of learning or studying.
• "Day day" is a playful English approximation of the Chinese word for "every day," which is "天天."
• "Up" is used to suggest improvement or moving upwards, which is the direction one would "go" when improving.

So, the phrase literally means "study well, improve every day," but it is used more for its catchy and amusing sound than its literal meaning.
