1, geographical advantage: Harbin can radiate 25 trading ports, with a long history, a strong atmosphere of Sino-Russian business exchanges and rich Russian talents, which provides convenient conditions for its development.

2. Limitation: In the past, cross-border e-commerce merchants traded ordinary personal parcels by postal mail, which took a long time to transport. After the completion of the Grand Passage, the time limit for goods transportation will be shortened from 40 to 60 days to 25 days, so as to ensure the rapid completion of transactions and accelerate the withdrawal of funds.
