in this morning，i hear a song from Jason zhang. do you know him？

Yes, I'm familiar with him. Jason Zhang, also known as Zhang Liangying, is a Chinese singer and songwriter. His voice is well-known for its powerful and distinctive quality. He gained widespread recognition after participating in the third season of the Chinese singing competition "China's New Song" in 2015, where he was named "The Voice of China." Jason Zhang has released many hits and is quite popular among fans for his soulful and emotive songs.

However, there seems to be a small grammatical error in your sentence. It should be corrected to:

"In the morning, I heard a song from Jason Zhang."

Remember, when specifying the time of day, it's important to use definite articles like "the" before them (e.g., "in the morning"). Keep practicing, and if you have any more questions about English or music, feel free to ask!
