36 years old. Mainland China actor Da Long, whose nickname is Liu Chunlong, was born on November 9, 1988. He graduated from the Central Conservatory of Music (distance education) and his works include "Egg Fried Rice" and so on. When calculating age, you need to subtract the birth time from the current time, that is, 2024-1988 = 36 years old. Because it has not reached November 9, 2024, it is 36 years old.
