The general manager, Mr. Hong Hao, showed me some photos (see below) reflecting this year's work conducted by Hong Ri Company. He told me that the company carried out one large vetiver project this year, and it is in the campus of Huizhou University. This is a newly-established univeristy, located in the central part of Guangdong Province, about 160 km away from Guangzhou. He also said that the project lasted so long, from April 23rd to August 13 due to the influence of bad weather, mainly storms.

The whole project is quite large with a total area of nearly 30 000 m2, composed of 4 parts. Here I submit you two main parts. The first part is located in the back of a building; the first two photos were the background, and the latter two were the appearance after vetiver was planted. The second part is one section of long side-slope of the stadium; the first two photos were the background, and the latter three were the appearance after vetiver was planted. He aalso told me that the benefits were not bad and the univeristy was satisfied with the present result.

The average cost of vetiver vestablishment was appoximately Yuan 9 (US $1) per square meter. In the order of US$ 0.5 -1.0 per linear meter of hedgerow.
