Baiyun Internation Airport(Line metro) to Xiobel, Taojin, and Ximenkou stations?

1. Xiaogang Metro Station via line 2 is about 700 meters to the east end of Huangshidonglu.
2. Well, these three stations nearly have the same distance from the airport.
Xiaobei Station: You need to take metro line 3 to Jiahewanggang Station and transfer metro line 2 to GZ Railway Station. Then take metro line 5 to Xiaobei Station.
Taojin Station: It is only 1 stop between Xiaobei and Taojin via line 5.
Ximenkou Station: You can take metro line 3 to West Tiyu Road Station and transfer metro line 1 to Ximenkou Station.

Tq Dick. It looks like Ximenkou is a better choice, since from the airport I need to change the train only once instead of twice for Xiobel and Taojin.
For retail shopping for clothing(including silk), leather, household equipments, electronics, someone recommended the following:
1.Guangzhou Shisanhang Clothing Market Area (wholesale buyers only?)
2. New China Building (Xinzhongguo Dasha) on Shisanhang Lu (wholesale buyers only?)
3. GZ White Horse Clothing Market, alongside the GZ Railway Station(one of dozens of markets in that area, all specialising in different styles )
4. Gaodijie Wholesale Market, just next to Beijing Lu, Gaodijie Market (mainly retail underwear )
5. First Tunnel Clothing Wholesale Center (mainly Muslim style clothes )

Are all these places accessibly by metro/subway/train? I am trying to avoid the bus, taxy( safety, language problems?) and too much walking(for an elderly couple).

1. Shisanhang Clothing Market is near Yide Road Metro Station on line 6, which is only about 620 meters’ walking.
2. New China Building is only about 170 meters from the Shisanhang Clothing Market.
3. White House Clothing Market is only about 350 meters from the GZ Railway Station on the metro line 2 and line 5.
4. Gaodijie Wholdsale Market is around 500 meters from Beijing Road Metro Station on line 6.
5. First Tunnel Clothing Wholesale Center is about 300 meters from the GZ Railway Station on the metro line 2 and line 5.
