Here's a breakdown of the meaning:
* 上 (shàng): means "upper", "above", or "top"
* 上 (shàng): means "upper", "above", or "top"
The repetition of "shàng" emphasizes the idea of being at the very top or the best. It's similar to how in English we might use expressions like "top-notch" or "superb".
However, it's important to note that "shang shong" is not a common or formal expression. It's more likely to be used in informal settings or in online slang.
For a more formal way to say "excellent" in Chinese, you can use expressions like:
* 很好 (hěn hǎo): very good
* 很棒 (hěn bàng): great
* 优秀 (yōu xiù): outstanding
* 卓越 (zhuó yuè): excellent
* 一流 (yī liú): first-rate
