On July 21, a group of us including 时真、李静、广财、扬之 paid a half-day visit to Research Institute of Tropical Forestry (RITF) of  Chinese Academy of Forestry. RITF is located within 15 minutes away from our institute. We had a quite formal meeting between the SKLOG  people and the 南岭北江源生态实验站. Professors We Zhongmin (吴仲民）and Zhou Guangyi (周光益）has been my long time friends. Guangyi gave a detailed introduction of their field facilities across Nanling and their research on the response of forestry ecosystem on climate abnormalities.   I gave a talk introducing organic geochemistry and SKLOG . The two sides then had plenty discussion on potential collaborations. I summarized the possibilities as: i) tree rings for ¹⁴CO₂; ii) sediment records  of historical cold/frozen events and ecosystem response; 3) forestry breath of ¹⁴CO₂; and 4) BC/DBC in fired forest ecosystems in Nanling. We had a lot of drink after the fruitful discussion which last almost 3 hours. Li Jing would be very happy to receive a very precious gift from Professor Wang Xu of RIFT which are preserved tree rings of Guangdong Pine collected from each 3 altitudes from the South and the North aspectes of Nanling!  Happy life and enjoyable gathering!

PS: On July 5-8, invited by Zhongmin, I had opportunity to go with a group of experts to the RIFT Nanling Observatory facilities across the mountains. I had a deep impression on the trip and the facilities; and was figuring ideas in mind for  potential collaborations/further explores. Now it is clear. I wrote a Ci poetry (词）recording the great trip, below, with many nice poctures in the field.

【浣溪沙 南岭记行】

其一
雨后江山肆意骄，白烟恋翠瀑声潮。轻车六月、路迢遥。
绿谷西瑶何所见？得参样地九方坳。层流渗漏、计厘毫。
其二
武水源流莽岭峤，分湘界粤入云霄。松杉针铁 、竞粗豪。
百里平湖舒两岸，浊溪润草粉蝶娆。红军故事、乐昌谣。 ​​​​
​其三
青嶂山青野草茅，玲珑铁塔过树梢，精心适配、水林交。
迤逦闲心说笑语，江山如画逝流韶，烧鹅就酒、酹滔滔。 ​​​

Prof Wang Xu (王旭) transferred the precious tree ring samples from Nanling (South and North aspects, each at 3 elevations, from ca. 800-1500 masl) to Li Jing.

得参样地九方坳。（西瑶样地共有9块）

分湘界粤入云霄。

雨洗江山，白烟恋翠。

浊溪润草粉蝶娆。（邹滨高工赠南岭植物和蝴蝶志大作。）

高峡平湖舒两岸。（乐昌峡谷，因建水库而两岸舒缓）

长征故事、乐昌谣。

白烟恋翠瀑声潮。

松杉针铁、竞粗豪。（广东松-华南五针松、长苞铁杉为南岭树轮研究最好的树种）

玲珑铁塔过树梢。

精心适配、水林交。

青璋山青野草茅。（茅草是南岭最广泛的一年生植物，青璋山管理处可安排全广东同步采样。又，此处进山之路已被茅草交盖）
