An investigation into the furore over actress Huangyang Tiantian being pictured wearing what appeared to be luxury earrings has concluded that they were in fact imitations of a high-end brand.

The teen actress sparked controversy in May after posting photos in which she wore earrings reportedly worth millions of yuan, raising questions about the legitimacy of her extravagant spending, given her family's civil servant background.

The earrings were eventually found to be a gift from a friend of her mother in 2016, made of glass and imitating a designer brand. No records of a purchase of the authentic items have been found at the brand's stores in China at this time.

A preliminary investigation from the joint task force which was released in late May, confirmed that her father was not involved in any post-disaster reconstruction projects during his tenure in Ya'an, Sichuan.

But they did find his two rule violations, namely unauthorized business activities while employed during his employment by the government and deliberate concealment of a violation of China's former two-child policy.

The supervisory authority has confiscated 30,000 yuan ($4,176) in illegal gains obtained from a company by Huang's father, with the surname Yang, when he was working as a civil servant. Since he has already resigned from his position, no further administrative penalties will be imposed.

Regarding the violation of the family planning policy, since Yang has resigned and the relevant penalties have been abolished, no further action will be taken.

The investigation also found that there was no evidence that Yang had profited from post-disaster reconstruction projects or charitable funds during his tenure in Ya'an.
