哪 vs. 哪里
What´s the difference between the questions 哪 and 哪里?
If I want to ask my daughter where her book is, should I better use the pattern 你的书在哪儿？ or 你的书在哪里？
Or doest 里 imply that the thing we are looking for should be inside something, e.g., inside a bag or a box?
If I play hide-and-seek with my daughter, should I better ask 我的女儿在哪儿？ or 我的女儿在哪里？
