无所谓 is a commonly used phrase in Chinese that means "it doesn't matter" or "it's all the same to me." It can also be translated as "it's of no concern" or "it doesn't make a difference." The phrase comes from the Chinese characters 无 (wú), which means "no" or "not," and 所谓 (suǒwèi), which means "so-called" or "alleged."

Here are some example sentences in English and Chinese:

"What do you want to eat for dinner? It doesn't matter to me."

"晚餐你想吃什么？无所谓。"

"Do you want to go to the movies or stay at home? It's all the same to me."

"你想去看电影还是呆在家里？无所谓。"

"Should we take the bus or walk to the park? It doesn't make a difference to me."

"我们是坐公交车去公园还是走路？无所谓。"
