Chi Sau uses connected speed but unconnected speed will always be faster than connected speed. This is the reason why boxers can be so dangerous. They use unconnected speed.

The meaning of Chum Kiu is to search for the Bridge. Contact awareness is not something to be avoided by the VT Practitioner but neither should they seek to endlessly remain in contact with their opponent or partner.

Within Chi sau one must be able to disengage and use unconnected speed to one's advantage and then reconnect if necessary, whilst again seeking to be "free" and to use the unconnected speed.

Unconnected speed conforms to the motto of Lut Sau Jik Chung - when the hands are freed of obstacles attack instinctively. When using Lut sau Jik Chung one does not seek to "stick". It is obvious that when the way is clear one should be hitting. If the correct elbow connection and placement has been trained then one's Centre will be covered in the process of hitting conforming to the motto of "attack and defence in one"

Another observation is that a Ving Tsun Practitioner that spends year upon year engaged in Chi Sau alone may well be caught out and hit hard and hurt on the street, if they do not understand unconnected speed.

A Ving Tsun Practitioner should be able to make use of contact to read energy and find the gaps to hit. However when the opportunity arises to hit they must be very aggressive and channel all their strikes into one point to completely overwhelm the opponent.
