那不只是释放实际的指针，而不是释放每个字符串本身正在使用的内存吗?

won't that just free the actual pointers and not the memory each string itself was using?

是的.

我如何完全释放内存

How do I completely free the memory

通过遍历数组并在 释放数组本身之前一一释放每个字符串.例如

By looping through the array and freeing each string one by one before freeing up the array itself. E.g.

for (i = 0; i < SOMETHING; i++) {
    free(list[i]);
}
free(list);
