Nevertheless, when Lin and his team first arrived at the project site, things were not as easy as they had imagined, including the temperature of groundwater that is too high for the natural coolant to help mushrooms grow properly.
Overcoming technical difficulties, Lin's team managed to establish a Juncao mushroom production line with a mini-laboratory, which is currently capable of producing some 30,000 kilograms of mushrooms annually. As the project further evolves and involves more farmers and local businesses, the output is expected to rise significantly, said Lin.
"One method is growing mushrooms in controlled indoor environments, while the other one is growing them in trenches beneath trees, and both have been a success," Lin said.
In a bid to attract more Fijians to this new industry, Lin's team has organized a series of training courses and trained nearly 300 local Juncao technicians, who can further get families and friends involved in mushroom production.
Aside from being used as mushroom "soil", the high-yielding Giant Juncao Grass brought to Fiji by Lin can also be processed, stored and used as animal feed directly, which comes in handy especially during the dry season.
"People who are interested in the commodity (Juncao mushroom) will benefit because it's a simple technology where one does not need to purchase acres of land to cultivate but plots are required with short time to plant and harvest," Miliakere Nawaikula, a former senior official with Fiji's Ministry of Agriculture has said.
During one training course held last year, two mushroom importers told Xinhua that they are "very interested in" growing and selling Fijian Juncao mushrooms, which are less expensive compared with foreign ones.
Inia Seruiratu, Fiji's minister for agriculture, rural and maritime development, agrees.
Calling China as "a friend of Fiji and a key development partner", Seruiratu has told Xinhua that Fiji spends its foreign currency reserve to purchase mushrooms and animal feed from overseas, therefore by promoting the local Juncao industry, the country can shrink its import bills and increase local farmers' incomes, which benefits poverty alleviation efforts.
Moreover, Seruiratu said, the project can greatly help Fiji in the fight against climate change since the Giant Juncao Grass has been doing very well in terms of soil conservation.
The Juncao project is among a range of Chinese development assistance to Fiji, including road upgrade projects, a rice project to improve Fiji's food security and farmers' livelihood, a sewing machine project where China has donated over 2,200 sewing machines to Fiji's rural and disabled women to help them with job opportunities, as well as other projects, which as a whole have been assisting Fiji on the development path that the Pacific island country has chosen by itself.
