There are some free divination on WeChat, that is, reading palms. Is it a lie?

Fortune-telling is superstitious and unscientific, and the most expensive things in the world are free. Free things only attract some people looking for discounts by playing a gimmick at first, so these free fortune tellers are not credible, so it may be easy to say something misleading and then guide people to buy something good or bad, thus generating interest relations.
