Twelve Siberian tiger cubs are charming visitors at a park in northeast China's Heilongjiang Province, as they continue to grow stronger under round-the-clock human care. Born earlier this spring at the Siberian Tiger Park in Harbin, capital of Heilongjiang Province, the 12 cubs are now actively exploring their surroundings - sniffing, tumbling, and displaying playful behavior that has quickly captured public attention. Currently, the largest of the 12 Siberian tiger cubs is nearly two months old, while the youngest is about to reach one month. Due to insufficient milk from their mothers, the tiger cubs and eight African lion cubs in the park are being hand-fed by caregivers. From May to June each year, the Siberian tiger enters its peak breeding period. With the breeding peak approaching, the park expects the total number of Siberian tiger cubs born this year to exceed 20. The Siberian tiger, a species on the national first-class protection list in China, is also one of the flagship species for global biodiversity conservation.
