I applied for chinese VISA, to visit Canton phase-1 during 15th to 19th April. However, my application was rejected twice from consulate in Mumbai. The reasons given were 1. 'no original invitaion' (the canton fair people issue an e-invitation), 2. ' flight ticket not appropriate' (my ticket is for Hong Kong (11th April) & return to Mumbai (23rd April).

Now, can I apply for VISA again in HongKong? What documents do they need?
