1. Buckle first the suspending button onto the triangle framework.
2. Suspend the framework with iron line and get horizontal line ready.
3. After the framework is installed ready, insert the square ceiling directly into the triangle framework, (The edges of the square plate are inserted into the gaps of the keels).
4. As for putting together the quadrate boards, a slight pressure is enough to make them tightly linked, make sure the seams formed along the transverse and longitudinal lines are orthogonal.
5. Be sure to wear gloves when installing board surfaces. In case any finger prints or any smear are left, you can use detergent with hot water to clean and wipe clean.
