Rising temperatures in his hometown might not be the most exciting topic of conversation, but for Wu Weijiang, they may well become something worth noting in the report he submits to the Party committee of his village.

It is a common practice for applicants to report what they think or what they do in their daily lives before they are formally accepted as members of the Communist Party of China (CPC).

Wu, a villager from southwestern China's Guizhou Province, has recently been occupied by what's happening in the fields where he and his fellow villagers grow Chinese herbs, which are used to produce traditional Chinese medicine.

In his latest report, Wu specified some precautionary measures that could be taken in the field, as changes in the weather may threaten its profitability.

At 35 years old, Wu is widely respected by his fellow villagers as a "business elite". In October of last year, he sent an application to a local committee of the CPC, saying that he wished to become a CPC member.

Before returning to his hometown in Guizhou's Dafang County, he worked in southern China's industrial city of Guangzhou for eight years. During his stay there, he made nearly 48,000 yuan annually, almost eight times as much as the average Chinese farmer in 2010.

It was a coincidence that Wu decided to quit his job in the cities and return to his hometown to work as an herb farmer.

In 2007, when he returned to his hometown for the Chinese Lunar New Year, Wu noticed that Chinese herbs were increasing in popularity among his fellow villagers. Wu observed that the herbs were capable of surviving in very dry conditions, making them easy to grow in even the driest areas.
