I think you should try reading the book, Love of Maple Leaves in Canada. Although it was a short story, the plot was very rich and interesting. It was a treasure book for starting a business. At the same time, he could also take a look at " The Daily Life of a Cheater." The protagonist of this novel was a cheat entrepreneur. His style was relaxed and leisurely, and he described his whimsical and innovative style. I hope my recommendation can help your brother and help him succeed in his business faster. I wish your brother's career every day and hope that your cooperation will proceed smoothly.😉
