If you’re working in a Chinese company, then you’d better be prepared for Chinese New Year’s Eve, the best time of the year to grab red envelopes on your WeChat group.

Chinese people give red envelope (hongbao, 红包) with money to their younger children and co-workers as a wish for good luck in the new year. Nowadays, Chinese people give hongbao using WeChat and Alipay, and it’s also the best time for Chinese companies to run on hongbao marketing bringing the term ‘hongbao wars‘.

Over the six-day Chinese Spring Festival period last year, 516 million people sent and received 32 billion digital red envelopes, which is 10 times the number as over the same period in 2015. Forecasters are expecting up to 100 billion digital envelopes to be sent and received around the world this year.

On Chinese New Year’s Eve day, your Chinese boss will send out a digital red envelope on WeChat group, which is then often grabbed by your peers in only a few seconds. Three things matter: your hand speed, the speed of your phone, and the network speed. If you cannot guarantee any of these three conditions, then these tactics might be useful to you to compete against your colleagues to secure your hongbao.

Use these apps or features on your phone to grab hongbao

1) iPhone

The latest version of iOS allows user to automatically grab the red envelope using iTools. How to: open the iTools click on the bottom bar “more”, open automatically grab red packets.
