Thanks for the info and rather assuring there are nice people left in Shanghai and the internet.
I admit that I am a total fool in forex or any modern edge finance kind of stuff. Im still stuck in the era of traveller’s cheque and the normal banking kind of stuff. But like many I had fears with the black market ways of sending money, but those Indians money changer prove reliable and efficient to me and I do hope they exist in Shanghai. If it was local Chinese that handles the black market money wiring then I would not be bothered by sending even a single cent. I somehow don’t trust the local Chinese there. But the Chinese elsewhere outside china especially the english speaking ones are great so far.
