Two weeks ago Alibaba released the latest version of the mobile app Alipay Wallet, challenging WeChat with a revamped lucky money giving feature. Alibaba yesterday also announced that the four Chinese tech companies in which it has invested (Weibo, Youku-tudou, Momo and Kuaidi) would join the fight against WeChat in this “digital lucky money war”. Social app Momo added a lucky money giving feature last month. The new way of e-coupon giving or sharing was inspired by WeChat’s lucky money giving feature. WeChat’s money giving feature was launched just before Spring Festival 2014, when Chinese traditionally give lucky money to the younger generations.
