The Shanghai market watchdog has supervised and sampled 66 batches of consumer goods — including infant and adult clothing, scarves, shoes and bags — sold via four major livestreaming platforms, among which 15 batches were unqualified, with a disqualification rate of up to 22.7 percent, Shanghai Market Supervision Bureau announced on Tuesday.

Ahead of the Double 11 shopping event, the local market watchdog reminds consumers to shop reasonably and don't trust livestreaming promotions blindly.

The unqualified goods were sampled from four major livestreaming platforms including JD.com, Pinduoduo, Tmall and Xiaohongshu (or Little Red Book), covering 65 brands including some well-known foreign brands like MANGO, Eland, and Disney, according to the Shanghai market regulator.

The unqualified items included those with incorrect product instructions (labels) or logos, pH values, color fastness to light, color fastness to acid and perspiration.

For instance, a batch of Eland clothing's pH value failed to meet national standards. 

Also, two batches of Disney backpacks with images of "Frozen" sold via Tmall were found to be unqualified due to oscillation performance. Eight batches of Jimmy Choo shoes sold via Tmall were reported with unqualified labels.
