Recently, went praying to the temples near my home and donated 10 packets of rice to the needy elderly. According to the Chinese metaphysics, by conducting good deeds, it will help the person destiny in all aspect. One of the element is wealth, which is related to investment.
In spite of that, there are companies doing it for publicity, which detest me. Therefore, we should not do it for a specific ill cause or intention, but with good faith to help the unfortunate one with an open heart.
