You should first set up an advertising account on INS, and then do a good job in advertising planning and material. INS is placed through bidding, so you should be familiar with all kinds of bidding rules before advertising can be effective. If it is too much trouble, I recommend Shenzhen Chuangzhu Company. They made an information flow advertisement for INS. They will communicate with you in the early stage, help you operate and launch, and get it faster than yourself.
