God helps those who help themselves.

Four Life Philosophies in Chinese Society
The first saying is called 'Skills Should Not Be Sold Cheaply'.
In Lanzhou, a bowl of beef noodles costs 15 yuan, selling 1000 bowls a day, resulting in an income of 10,000 yuan daily, and over 3 million yuan annually. If you ask the owner if he can sell you the recipe for the noodles, will he sell it to you? Many people master a skill that is the foundation for their family's survival and livelihood; would he easily sell it to you? This is called 'Skills Should Not Be Sold Cheaply'.
The second is called 'The Dao Should Not Be Transmitted Lightly'.
What does it mean that 'The Dao Should Not Be Transmitted Lightly'? In Buddhism, there are no thresholds for accepting students; it is benevolent. Anyone can enter my Buddhist gate, even if you are a murderer, but to be accepted as a student at home, you must go through an assessment. Military strategy can protect the family and the country, but it can also bring disaster to the nation. I must first choose people based on their moral character; I cannot transmit it lightly to others. This is called 'The Dao Should Not Be Transmitted Lightly'.
The third saying is 'Teachers Should Not Be Approached Casually'.
This means you should not casually ask a teacher to teach you something. For example, if you meet a master of destiny studies and you say, 'Master, could you casually take a look at my face?', asking the teacher casually to help you is disrespectful. The teacher will not take you seriously, and even if they look, it will be in vain. If you want the teacher to examine you, you should invite the teacher to do so. After the teacher finishes looking, you must remember to give them a token of appreciation. A token is what everyone should give; the teacher has cultivated in this field for decades and relies on it for a living. Why should they provide their services for free? If someone has changed your feng shui, altered your fortune, or changed your destiny, why can’t you give something back? Confucius would tell students to be more self-aware and to bring a dozen kilograms of pork to the teacher.
The last saying is 'Doctors Do Not Knock on Doors'.
Even if I know you are ill and I know what disease you have, if you do not seek me out for treatment, I will not take the initiative to treat you. Even if I am a good doctor, I will not actively seek you out to treat you. You must come to me for medical help; this is called 'Doctors Do Not Knock on Doors'. This is called the vastness of heaven, which does not nourish rootless grass; the Dao is broad and does not measure those without fate.
