Beijing has investigated and dealt with multiple cases of illegal toy stacking, cracking down on unlicensed products to strengthen the children's safety defense line.

According to the Beijing Municipal Administration for Market Regulation, as a trendy and popular children's toy, the market for building blocks continues to grow rapidly. However, the issues of product quality and safety have also become more prominent. Recently, enforcement officers from the Beijing Municipal Administration for Market Regulation conducted surprise inspections on major toy wholesale markets in the city through an integrated online and offline inspection model, cracking down on illegal activities in the children's toy market. They successfully investigated numerous cases of building blocks for children without the required 3C certification, effectively strengthening the safety of children's toy consumption.
