Any recommendation on apps/ YouTube videos on songs/ storytelling in mandarin suitable for 2yo toddler?

For App Store, try this: 兔小贝儿歌 There're songs, stories and poems. Can watch online or choose to download. For YouTube, try searching: 贝瓦儿歌 or 贝瓦故事 (If you can read Chinese well, can get more learning resources from their website: beva.com)
