是/有/在 你们好! I've recently started studying chinese and I'm having some troubles with understanding 是/有/在. As far as I know 在 requires the location to be after it whereas 有 is location + 有 + smth. 是 seems to be for going more on details. So I tried doing some exercise with these and I'd be glad if someone could check them up. 八号楼（在）九号楼旁边 图书馆东边外（是）文书店 学校里（有）银行 外文书店（是）什么地方? 书店里（有）多个学生 他（在）北京学习汉语 浴室（在）卧室旁边 你的左边（是）谁? 爸爸前边（是）孩子 If some of the sentences I built are weird or wrong please correct them 谢谢
