When you really have a better understanding of the research and development of pneumatic butterfly valves, and know exactly how to do it at this time, you will suddenly find that many things will have more possibilities. Especially for the future development of the company, after we have specifically considered the specific actual situation, and really defined our own development plan, you can completely find your own way, and eventually you will find that it is good for you to do your own research and development work in general. The understanding of the market and our own strength is crucial, and we cannot lack any aspect.
