Harvesting leeks, Zhao Rong was quite experienced in that.
Take this business of issuing cards, for example.
A simple card offer, how could that satisfy the vast needs of the leek public?
If Zhao Rong were the owner of Chen's Carriage Shop, wouldn't he immediately roll out a bunch of 'money-saving' services for the customers?
First off, he would set a time limit on this glaze Crystal Card, which right now, absurdly, doesn't have? At the very least, he would stagger them, offering a monthly luxury Silver Card, an annual extravagant Gold Card, and a lifetime supreme Crystal Card, with services increasing accordingly...
Then, during festivals and holidays, he would launch a big promotional sale on card subscriptions; if there weren't any holidays, he would invent some, otherwise how could he live up to everyone's enthusiasm for spending?
