Indochinese tiger cubs play inside their cage at the Hanoi Zoo June 22, 2011. Their mother, Mi, gave birth to four cubs in the morning of April 2, 2011, becoming the first tiger at the Hanoi zoo to be born and bred in captivity. Mi was born on the same day eight years earlier, on April 2, 2003, to Lam Nhi (which mean "Child of Forest"), a tiger that was confiscated from wildlife traffickers in Vietnam's central province of Thua Thien Hue.
