1, phoenix-eye bodhi itself will have some cracks, and the newly-acquired bodhi will leave dust and impurities. If you start directly, it will inevitably affect the effect of playing. The most correct way is to clean it up. Rub with rough towel cloth first, and then brush with hard bristles. If you want to keep improving, you can use crochet to pick those gaps, so as to clean up the Cheng Bodhi thoroughly.

2. Wear a cotton glove tray for one month after you can put it on, in order to make Cheng Yan Bodhi develop a clean oxide layer. During this period, pay attention to the timely replacement of gloves when they are dirty to avoid secondary pollution. When it's time to clean your hands, you can't get started directly. Wash your hands and dry them first to avoid a lot of sweat and moisture from entering the phoenix-eye bodhi. The time for washing should be controlled every day, not more than one hour, and let it rest for the rest of the time. Moreover, it's best to put it in the shade for a few days after playing, and repeat the operation, so as to make the patina harden.

3. After the patina is formed, it is still necessary to insist on playing, not giving up halfway, and occasionally brushing it to clean the gap impurities. After playing for 3-5 years, the phoenix-eye bodhi will have the effect of jade and form a thick patina.
