Recently, the supermarket is ready to open. How to choose an auspicious day in the old yellow calendar? I beg your help. thank you

Let's make it October 1st. Suitable: get married/get married/get married/get married/oversubscribe/cancel the contract/engage in a large-scale engagement/offer an engagement sacrifice/pray for children/have children/have a family/move/move away from the fire/open the market/open the business/open the business, set up coupons and hang plaques.

Auspicious and auspicious: the moon, morality and trinity, the king, the sun, the blessing and the heavenly doctor are blue dragons.

Green dragons protect each other and business is booming.
