The railway from Sichuan to Guangdong is too slow, so I suggest you fly directly to Guangzhou or Shenzhen. In Guangzhou, you can stay for about 3 days, visit the small waist in Zhujiang New Village, visit Beijing Road, Shangxiajiu Road Pedestrian Street, visit Chenjiaci, Grand Marshal&;s Mansion, Sun Yat-sen University, Shishi Cathedral, Whampoa Military Academy, etc. You can choose according to your personal interest, and you can definitely taste Guangzhou&;s delicious food, rice rolls, boat porridge and beef offal when you visit the scenic spots.
