THANK YOUB b / W d it h tt t dBamboo / Wood composites have attracted considerable interests as a sustainable

lt ti f t diti l t talternative for more traditional structure materials due to its outstanding mechanical

f d i t ll f i d hiperformances and environmentally friendship . I look forward to work together with all the

l h h i li ti t d lpeople, who have inclination to develop technology of green structures, to promote

ood/bamboo str ct res in China or anwood/bamboo structures in China or any other countries.
