The group had noticed the problems the staff, companies on the firing line were facing and how difficult it was for neighbor enterprises to recover their production, so it was time to take action to give their hands, including assisting our suppliers with production, purchasing masks and disinfectant supplies and offering tremendous support to the surrounding regions for fighting against the crisis.
