Tan Lang in the Parents Palace may invite questions about a parent's social connections, but an introduction is not permission to set your price or deadline. A relative might share your portfolio with a friend before any paid project exists. Another relative might promise delivery in three days when your schedule needs two weeks.
Use the Parents Palace to ask about the source of a contact, then the Career and Wealth Palaces to frame delivery and payment. Check the accompanying stars and aspects before making a reading. In practice, tell family members which introductions are welcome and reserve quotations, contracts, and confidential details for your own written exchange with the buyer.
