Very simple. There are many platforms where you can get coupons. Mi1mi1 Takeout in WeChat is a platform where you can get coupons for Meituan takeout, Ele.me takeout, supermarket fresh food, movies, and hotels, and you can get up to 66 yuan. You can receive red envelopes repeatedly every day, and they can also be combined with the merchant's full discount activities. In this way, the price of a big meal may only be a dozen yuan or a few yuan. I received a red envelope worth 20-13 yesterday. I spent 7 yuan to eat a large portion of braised chicken, which was quite cost-effective.
