Please do not add promotional material to Wikipedia, as you did to Mining machinery engineering. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion.   dibbydib (T ･ C) 04:52, 30 April 2020 (UTC)
