Pyramid selling is becoming rampant in the country despite a number of crackdowns over the years, officials said yesterday.

Officials from the Ministry of Public Security and State Administration for Industry and Commerce (SAIC) said the government is also considering revising relevant laws to impose heavier punishments against people engaging in such a selling practice.

"Pyramid selling, outlawed in the country about 10 years ago, is still serious. And it's growing," Gao Feng, deputy director of the ministry's economic crime investigation bureau, said.
