Tūn Zéi 吞賊
Tūn 吞 means swallow, Zéi 賊 means thief. Tūn Zéi means swallow the thieves. Thieves are bad, they come to your home and steal your things, so they are bad people. In this context, Zéi means bacteria, germs, dirty things and negative energy, which can all harm the body. We need to destroy them and so Tūn swallows them. This means that Tūn is our immune system which fights disease. Even when we are sleeping our Tūn Zéi will continue working to protect our body, finding any germ or bacteria and kill them – it swallows them. Of course it does not literally swallow them, it breaks them down and releases them out of the body. It is the same as Qìgōng 氣功 practise, if our Qì 氣 is strong, then it will find the problems in the body and release them out or at least make them weaker.
Fēi Dú 非毒
Fēi 非 means negative, Dú 毒 means poison. Fēi Dú means negative the poison. The term Fēi means making it negative or make it useless, so making the poison useless and releasing it is the purpose of Fēi Dú. When we are normal, then the Fēi Dú will find the problems, particularly with the temperature. Usually when we are unwell, we will feel cold, then Fēi Dú find the problem and Tūn Zéi will swallow it
