Is Guangzhou Jinsha painting deceiving people?

I also want to do this kind of painting, and I found several such part -time jobs on the Internet. Their advertisements are probably:

The Guangzhou **** Studio was established at the end of 1998. It is a medium -sized enterprise that combines the production and training of Jingtai Lan raw materials with Poping Crystal Technology. In October 2001, a "training center" of high teaching quality was established. After nearly 10 years of hard work, the studio has accumulated rich experience in organizing production, supply, and sales of Jingtai Lan raw materials. It has directly supplied the materials of many art colleges across the country all year round, and established a wide range of business relationships with more than 30 provinces and cities in the country and the production unit of Jingtailan. After several years of import and export trade, trade relations have been established with production and agents in many countries and regions in Southeast Asia. The company has built into the production and sales of Jingtai Blue glaze, Jingtai Blue Craft Products, Cloisonne Crystal Painting Glaze, Art Rock Color Glaze, Jewelry Silver Blue material, industrial enamel materials, daily enamel materials, copper wire, oxidation wire, copper, copper, copper, copper, copper, copper, copper Welding medicines, silver -free welding medicines, and comprehensive trading companies that integrate various related auxiliary materials.

It on Wednesday, I went to the crosses the craft studio across the club opposite Tianhe Park on Wednesday. I finally found it on the first floor of a residential community. It may be cut out of a house, there are more than ten square meters outside, and two tables of tables are placed. There are five or six students -like girls learning to paint with a young female teacher. Asked how to study, let me go in inside and say to the boss. There is a smaller room in it, there is a computer on a table, and a young girl. When asked about how to check it, he said that he did not charge tuition fees. Only 200 yuan of materials can be charged. You can learn in one or two days. You can take it home after learning. Of course, the material fee is paid.
I stayed there for more than half an hour. I watched a few large gold silk sand paintings on the humble house wall, and the standard of qualified sand paintings. At that time, I had a few doubts:
1, the studio that opened for so many years, the studio is still so small in such a cheap place.
2, the teacher -like makeup that teaches painting is like a gallery girl. There is no artistic temperament.
3, the paintings you learned there are only about 66 ~ 70cm. See the size of the square. It is a very simple pattern. How can you use the material cost of 200 yuan? If you make large paintings on the wall, the light material will be thousands of. How can the workmanship be sold?
4, I did n’t see anyone coming to paint, nor did I see the collected paintings.
I have a lot of questions, and I checked it on the Internet again before I know that these are all scams. They all cheat the cost of materials. Please see the answer here ./question/34650786
