20 19 went to Shenzhen to be a US group rider. I have a bad memory. How can I get familiar with the geographical location as soon as possible?

I think it's okay to look at the map and get familiar with the addresses of regional businesses, the dense spots of ordering customers, and the main streets and distribution areas of the site. Form a small map in your mind, where the merchants are, where the customers are, and where the distribution area is. Remember the delivery place, community, office building and school in detail. I hope it helps you.
