Two young giant-panda twins born in the United States have returned home to China, but are straggling to adapt to the language and food.

    The 3-year-old sisters, Mei Lun and Mei Huan, wens the first surviving panda twins to be born in the United States, and were returned to China from Zoo Atlanta on Nov. 5. But the pair still understand English belter than Chinese, and prefer American biscuits to Chinese bread.

    A zoo-keeper said that his main concern is that the pair are so addicted to American biscuits that everything they eat — from bamboos to apples — has to be mixed with biscuits. They even want to snack on (零食) biscuits when drinking water.

    The zoo -keeper is trying to wean them off their biscuit habit, gradually replacing the American food with Chinese bread. Mei Huan is adapting, but Mei Lun doesn't want to touch the unfamiliar bread.

    Mei Lun is the livelier of the two, often jumping onto the roof and hanging upside down from a rail, but her slightly younger sister Mei Huan is calmer, preferring to sit still, observe her new environment and occasionally snack on bamboo.

    A language barrier is also reported. While the pair respond to their own names, and understand some English phrases such as “come here,” they don't understand the Sichuan dialect of Chinese.

    The news caused some laughter on Chinese social media, with some users commenting that the pandas would soon get used to Sichuan's famously spicy cuisine.
