捣鼓一下午到现在还没解决的一句简单 SQL 语句求赐教：两张表关联查询求总数降序排列

表 member

表 city

查表 [ member as m ] 的数据总量 [ count(*) as total ]
顺带一起展示 city 表的 [ c.id,c.city_name,c.pinyin ]
关联另外一张表 [ left join city as c ]
关系是 member 的 m.from 关联 city 的 c.pinyin [ on m.from=c.pinyin ]
按照 c.pinyin 分组 [ group by c.pinyin ]
按照 total 降序排列 [ order by total desc ]

自己测试过以下语句
select c.id,c.city_name,c.pinyin,count(*) as total
from `city` as c
left join `member` as m on m.from = c.pinyin
group by c.pinyin
order by total desc
空记录的深圳本该是 0 ，但是查出来竟然是 1 。

select c.id,c.city_name,c.pinyin,count(*) as total
from `city` as c
left join `member` as m on m.from = c.pinyin
group by c.id
order by total desc
空记录的深圳本该是 0 ，但是查出来竟然是 1 。

select c.id,c.city_name,c.pinyin,count(*) as total
from `city` as c
left join `member` as m on m.from = c.pinyin
group by c.city_name
order by total desc
空记录的深圳本该是 0 ，但是查出来竟然是 1 。

以上三条 sql 结果一样，如下图

=================================

select c.id,c.city_name,c.pinyin,count(*) as total
from `member` as m
left join `city` as c on m.from = c.pinyin
group by m.from
order by total desc
少了 0 数据的深圳，数据不全。

select c.id,c.city_name,c.pinyin,count(*) as total
from `member` as m
left join `city` as c on m.from = c.pinyin
group by c.city_name
order by total desc
少了 0 数据的深圳，数据不全。

-- 表的结构 `city`

CREATE TABLE IF NOT EXISTS `city` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`city_name` varchar(30) NOT NULL,
`pinyin` varchar(30) NOT NULL,

INSERT INTO `city` (`id`, `city_name`, `pinyin`) VALUES
(1, '北京', 'beijing'),

(4, '深圳', 'shenzhen'),
(5, '未知', '');

请问如何写这条 sql 语句才能正确的查询如第一段想要的结果呢？
