Denizens of Shenzhen, a city neighboring Hong Kong, were the first among the mainlanders to spark an insurance bonanza in the special administrative region. But gradually, they found new business opportunities in promoting Hong Kong insurance products to fellow mainlanders.

Lyu Wei from Shenzhen works in the financial services industry. In the second half of 2014, he took up a part-time job of introducing Hong Kong insurance products to mainland buyers. Now, he leads a team of 20 people and serves more than 200 clients from Guangdong, Sichuan, Shanghai and even Beijing.

Since mainland agents and brokers need authorization of Hong Kong companies to sell the latter's insurance products, Lyu has teamed up with a Hong Kong insurance broking company. He is also constantly expanding his network of contacts in the mainland so he could find more buyers on Hong Kong's insurance products.
