Male, great-grandson of Bai Yanlin. A specialist in aerospace dynamics who risked everything to sneak back into China from overseas. He was born into wealth abroad but returned to serve his country. He smuggled critical research materials from a foreign lab and was nearly mistaken for a spy, locked up for over a month before earning military leadership's trust. He raised Bai Fumei in her past life. He is kind and gentle, especially toward Bai Fumei whom he calls Xiaomei.
