Totally understand that Chinese culture because everything selling within China can be fake.

But this can be rectified by simply opening an official A2M retail store in Australia. Chinese can place an order via wechat in A2M official store in Australia, then can choose either pick up from official A2M store in China or post directly to them. The store can also let them taste on the A2M different product & educate potential buyers the difference from other milk, similar to Apple store concept, in a smaller scale.

Those international students can still sign up as a A2M resellers if some uneducated Chinese just trust their network and cannot order online themselves. They still can profit. Diagou still can exist. Just boarder closure is no longer an issue.
