From the very beginning, group buying websites have created a lot of noise. The "Battle of a Thousand Group-buying Sites" is no longer sufficient to describe the current chaotic situation in the group-buying industry. The rapid expansion of the domestic group-buying market is largely due to the low threshold and inadequate funds, which naturally leads to a mix of good and bad players in the market. The Ministry of Commerce's International Electronic Commerce Center has completed its first credit certification and rating work for group-buying sites. Among the more than 300 group-buying sites, only about 20 have received the first batch of credit certification qualifications. This fact also serves as the best footnote to the验证 unchecked growth of group-buying sites in China.
