How to make bows and arrows with bamboo rope glue?

Three-year-old Phyllostachys pubescens was cut into bamboo blocks of appropriate size and dried in the shade for half a year (about 1m 7 in length and 3-4 cm in width). Use a plane or kitchen knife to trim the bamboo surface to be thick in the middle and thin at both ends. It should be natural classification, not too fine. Two pieces of bamboo treated in the same way should be opposite, compacted with glue, and chords should be made at both ends after the glue dries.
