I'm Indian. I've taken Chinese & Malaysian visa. Entering China at Guangzhou via Kuala Lumpur. Leaving China from Hong Kong via KL to India. I am about to purchase air tickets for these trips. But since I have not confirmed date of travel to Hong Kong from Guangzhou, I plan to buy it once in China. Is it OK to enter with return ticket from Hong Kong though I enter at Guangzhou? Kindly reply urgently. Many thanks in advance for your kind assistance. Anees.
