Group firing system for firework unit, wherein it has 1-2 paper fuse tubes, which are assembled with other shot tubes. While both ends of the paper fuse tubes have male socket and female socket, so each firework unit could be connected to a firework group through soft fuse hose which contains a fuse inside. There are two firing systems, i.e. series connection and parallel connection.

The invention claimed is: 1. A group firing system, comprising: a plurality of fireworks units, each including a plurality of firing shot tubes, the firing shot tubes having a first firing shot tube and a final firing shot tube, the firing shot tubes connected with each other through a plurality of inner fuses; and wherein: a lower fuse tube and an upper fuse tube are disposed in each of the fireworks units; each end of the lower and upper fuse tubes has a socket, the fuse tubes connected to each other with a plurality of soft fuse hoses inserted in the sockets for forming a fireworks group, each of the soft fuse hoses containing a plurality of outer fuses; and a first fuse is provided in the lower fuse tube, and a final fuse is provided in the upper fuse tube, in which the first fuse linked with the inner fuse from the first firing shot tube and the final fuse linked with the inner fuse from the final firing shot tube. 2. The group firing system of claim 1, wherein the lower fuse tube is positioned in a lower section of the fireworks unit, and the upper fuse tube is positioned in an upper section of the fireworks unit. 3. The group firing system of claim 1, wherein each of the soft fuse hoses contains the outer fuse inserted in one of the sockets of the lower fuse tube of the fireworks unit, the soft fuse hose contains the outer fuse inserted in one of the sockets of the upper fuse tube of the fireworks unit and inserted in one of the sockets of the lower fuse tube of the other fireworks unit, the soft fuse hose containing the outer fuse inserted in one of the sockets of the upper fuse tube of the other fireworks unit, so that the group firing system is connected in series attached fashion. 4. The group firing system of claim 1, wherein the soft fuse hose contains the outer fuse inserted in one of the sockets of the lower fuse tube of the fireworks unit, the soft fuse hose contains the outer fuse inserted in the other socket of the lower fuse tube and inserted in one of the sockets of the lower fuse tube of the other fireworks unit, the soft fuse hose contains the outer fuse inserted in the other socket of the lower fuse tube of the other fireworks unit, so that the group firing system is connected in parallel attached fashion. 5. A fireworks unit, comprising: a plurality of firing shot tubes, the firing shot tubes having a first firing shot tube and a final firing shot tube, the firing shot tubes connected with each other through inner fuses; and wherein: a lower fuse tube and an upper fuse tube is disposed in the fireworks unit; each end of the lower and upper fuse tubes has a socket; and a first fuse is provided in the lower fuse tube and a final fuse is provided in the upper fuse tube, in which the first fuse is linked with the inner fuse from the first firing shot tube and the final fuse is linked with the inner fuse from the final firing shot tube.
