Ши Лэ
Shi Hong was Shi Le's second son, by his concubine Consort Cheng. Unlike the militaristic Shi Le, Shi Hong was known for his literary studies and kindness. After his older brother Shi Xing (石興) died, Shi Le made him his heir apparent. In 330, after Shi Le declared himself first "Heavenly Prince" ("Tian Wang") and then emperor, he created Shi Hong crown prince. Shi Le, concerned that his powerful nephew Shi Hu, a ferocious general, had too much power, began to transfer some of Shi Hu's power to Shi Hong, but this only served to aggravate Shi Hu, who already resented Shi Hong for being younger but yet crown prince, believing that, as the general who contributed the most to Shi Le's campaign successes, he should be crown prince.
