Tourist routes from Guangzhou to Hangzhou and Suzhou

If the air ticket fee is controlled at 2000 yuan/person, the air ticket from Wuxi to Guangzhou is much more expensive than that from Hangzhou to Guangzhou. First sit in Hangzhou, visit the West Lake, then go to Xitang and Zhouzhuang, then go to Suzhou, visit the gardens, then go to Wuzhen, then go back to Hangzhou, visit Hangzhou, and then fly back to Guangzhou.
