Shang Hui's technical training is not true. Hangzhou Shang Hui Technology Co., Ltd. launched a cross-border e-commerce course on Youzan platform and made false publicity. On the platform, minors and the elderly are induced to participate in cross-border e-commerce charging training courses, claiming to be official cooperation training with shrimp cross-border e-commerce platform. Later, it was verified by the official customer service of shrimp skin that she was a false propaganda, demanding a refund and taking off the products.
