有人在我的油管频道作了以下留言：Is this really da tou cai Ive having trouble finding any in the asian grocery stores but they do carry this one 请帮我用英文回复一条留言包含以下意思：请问你想要用da tou cai来做什么？你图片显示的罐装酸菜在中国通常用作拌饭的小菜。

Thank you for your comment! Da tou cai is commonly used as a side dish for rice in China. May I ask what you are planning to use it for? If you're looking for da tou cai to make a specific dish, please let me know and I can try to help you find it.
